Comparitive study on rcc and composite (cft) multi storeyed buildingseSAT Journals
Abstract In India reinforced concrete structures are mostly used since this is the most convenient & economic system for low-rise buildings. However, for medium to high-rise buildings this type of structure is no longer economic because of increased dead load, less stiffness, span restriction and hazardous formwork. So the structural engineers are facing the challenge of striving for the most efficient and economical design solution. Use of composite material is of particular interest, due to its significant potential in improving the overall performance through rather modest changes in manufacturing and constructional technologies. Steel-concrete composite columns are used extensively in modern buildings. Extensive researches on composite columns in which structural steel section are encased in concrete have been carried out. In-filled composite columns, however have received limited attention compared to encased columns. In this study E-Tabs nonlinear software is used for simulation of steel concrete composite (CFT) with steel reinforced concrete structures (RCC) of G+14, G+19 and G+24 stories each are considered for comparative study. Comparison of parameters like time period, storey displacement and storey drift is done. Keywords: Composite CFT columns, bracings, shear wall, time period, storey displacement and storey drift.

Dynamic analysis of steel tube structure with bracing systemseSAT Journals
Abstract Nowadays, competition towards rise of tall steel structures made certain factors are compulsory like serviceability and comfort of human relating to lateral loads caused by wind or earthquake. Earthquake is dangerous to the living beings in terms of its effects on manmade structures. Structures like tall buildings are built to resist gravity loads. However many tall buildings are not so resistant in lateral loads due to earthquake so need an improvement in resisting lateral loads. So there are many structural systems which resist lateral loads by varying orientation, addition of different structural systems. Like steel tubular structural system is considered and compared for their results against lateral forces and also by providing mega bracing system and diagrid bracing system. In this dissertation work, four structural systems are considered in which one is framed structure and rest are tubular system with addition of different bracing systems as mega bracing and diagrid bracing system. For the purpose 45 storey steel structure with rectangular plan of dimension 44mx24m uniform throughout the height is considered and analyzed for gravity and lateral loads using ETABS software. Its intention is to obtain the functioning characteristics like displacements, storey shear, time period, frequency, peak displacement and peak acceleration in both x and y direction to get most economical structure in all ways. Results shows that the steel tubular structure with mega bracing system performance is much better than the framed structure, tubular and tubular structure with diagrid bracing system. Keywords: Steel Tube Structure, Mega Bracing, Diagrid Bracing, Dynamic Analysis, ETABS, Time and History Analysis.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

M.Tech PPT.pptx
1. ABSTRACT
•The project entails the planning, analysis, and design of an institutional
building made of steel-concrete composite materials.
•The proposed structure is a G+3 structure with 3.5m floor heights. The
building's overall plan dimension is 15m x 12m.
•The analysis and design process includes structural planning, load
calculation, 3D modelling with STAAD-Pro, and the design of a
composite slab, beam, columns, and RC foundation.
2. OBJECTIVE
•Steel consumption in the building sector in India is quite low due to lack
of expertise and construction procedures when compared to several
emerging nations.
•It is clear that composite sections made of steel encased in concrete are
now an economical, cost-effective, and time-effective option in
important civil mega projects such as bridges and high-rise buildings.
3. COMPOSITE STRUCTURES
•When a steel component is joined to a concrete component, a composite
part is generated.
•In such a composite material, the relatively strong compression strength
of the concrete balances the high tension strength of the steel.
•As each material is designed to its maximum potential, composite Steel
Concrete construction is both efficient and cost effective.
•The main appeal of such construction, however, is dependent on having
an efficient connection of the Steel to the Concrete, and it is this
connection that permits a transfer of forces and provides composite
elements their distinct behaviour.
4. SHEAR CONNECTORS
•Shear connections are critical in steel concrete construction because
they combine the compression capacity of the supported concrete slab
with the compression capacity of the supporting steel beams.
•The behaviour of composite beams under transverse stress is illustrated
in two extreme situations.
1.Full interaction - Assume that the beams are connected by an infinitely
stiff shear connection. Because the slip strain is now zero everywhere.
2.With no interaction - It was previously assumed that there is no shear
link between the beams and that they are simply stacked on top of one
another but operate independently.
5. TYPES OF SHEAR CONNECTORS
•Rigid Shear Connectors - As the name indicates, these connections are
extremely stiff and can withstand only minor deformation while resisting
shear stress.
•Flexible Shear Connectors - Flexible shear connections are made up of
headed studs, channels, or tees that are welded to the top flange of steel
beams. They get their stress resistance from bending and go through a lot
of deformation before they fail.
•Anchorage Shear Connectors - Anchorage shear connectors are used
to resist longitudinal shear and to prevent separation of the beam / girder
from the concrete slab at the interface through bond.
6. PROFILED DECK
Advantages
•Steel weight savings range from 30% to 50% as compared to non-
composite construction.
•Greater rigidity of composite beams results in shorter depths for the
same span. As a consequence, lower storage heights are appropriate,
leading in savings in classing costs, wind loading reductions, and
foundation cost savings.
•Faster rate of construction.
•It serves as a working platform and supports loads during construction.
7. PROFILED DECK
•It creates sufficient composite activity with concrete to withstand the
given loading.
•It transmits in-plane stress to vertical bracing or shear walls via
diaphragm action.
•It keeps the volume of concrete in the stress zone stable.
•It spreads shrinkage forces, preventing significant concrete cracking.
8. PROFILED DECK
Design Procedure
•Calculate the effective length of the span.
•Compute factored moments and vertical shear.
•Check moment adequacy.
•Check vertical shear adequacy.
•Check deflections.

19. SUMMARY & CONCLUSION
•A G + 3 structure of plan dimensions 15m x 12m has been analysed, designed
and optimised.
•Though, the cost comparison reveals that Steel-Concrete composite design
structure is more costly, reduction in direct costs of steel-composite structure
resulting from speedy erection will make Steel- Composite structure
economically viable. Further, under earthquake considerations because of the
inherent ductility characteristics, Steel- Concrete structure will perform better
than a conventional R.C.C. structure as the stiffness is more compared to RCC.
•For analysis STAADPro software has been used. Manual design have been
carried out for steel composite building and compared with the staad model.
•Sufficient insight into the analysis and design of Steel-Concrete composite
structure which is an emerging area has been gained.
•Immense confidence has been gained in the analysis and design of a multi-
storeyed structure using STAAD Pro software which will benefit me as I step out
of the portals of the college.
