A truss is a structure composed of straight structural elements arranged in a triangular pattern and connected at their ends. Trusses are commonly used in buildings to support roofs, floors, and internal loads. The main benefits of trusses are that they allow for long spans, are lightweight, have reduced deflection compared to solid members, and can support significant loads. However, trusses also have higher fabrication costs. Common types of trusses include king post, queen post, Warren, Howe, Pratt, and Parker trusses.
Arch is a curved structure designed to carry loads across a gap mainly by compression. The mechanical principle of the arch is precisely the same as that of the portal frame. The straight pieces of material joined by sharp bends are smoothed into a continuous curve. This increases the cost of construction but greatly reduces the stresses.

BEHAVIOUR OF STEEL STAGGERED TRUSS SYSTEM UNDER SEISMIC LOADINGIAEME Publication
Staggered truss system is a prospective steel structure system for multi-story and high-rise
buildings. The staggered truss framing system arose from the use of system design techniques to
improve efficiency in building construction. Staggered truss systems have proved to be effective in
integrating the structural and mechanical requirements. In addition, cost reductions arising from
reduced steel tonnage and reduced building volume may be achieved from the use of these framing
methods. The purpose of this project is analytical investigation on the behavior of an 8-storey steel
staggered-truss system using the ETABS software.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
A Strategic Approach: GenAI in EducationPeter 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.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
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.

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

17. Height – 324 m
Located in Champ de Mars, Paris
Iron Lattice Tower
Named after its engineer, Gusatve Eiffel
The tower has three levels for visitors
Restaurants on the first & second
Observatory on the third
Construction started 28 January 1887
Completed 15 March 1889
Opening 31 March 1889
18. Design of the Eiffel Tower was
originated by Maurice
Koechlin and Émile Nouguier, two
senior engineers
Gustave Eiffel
Described by Koechlin as "a
great pylon, consisting of four
lattice girders standing apart at the
base and coming together at the top,
joined together by metal trusses at
regular intervals"
Initially Gustave Eiffel himself
showed little enthusiasm, but he did
sanction further study of the project
It was only after the head architect,
Sauvestre added decorative arches to
the base, a glass pavilion to the first
level, and other embellishments did
the design grab Gustav Eiffel’s praise
Stephen Sauvestre
20. The foundation of the Eiffel Tower was very
important because it needed to be able to
successfully hold a load of about 10,000 tons.
As a result of the weak soil, Gustave Eiffel
created a two-system foundation for the
Eiffel Tower.
The use of casings alllowed the
engineers to take up the
challenge and avoid water leaks
while reinforcing the foundations
with the adding of brickwork and
concrete. It only took four months
for the foundations then the
building of the pillars started.
The North and West pillars of the
Eiffel Tower were close to the
Seine River. It caused serious
problems to the foundations since
a stable soil was needed to build
the Eiffel Tower.
Use of Caissons
21.
22. The Eiffel Tower’s base is composed of four
legs. In these legs are 2 anchor bolts that are
each 26 feet long and 4 inches in diameter.
One part of Eiffel’s plan for the foundation of
the structure was the placement of a
hydraulic jack. The hydraulic jack was used
to enable the raising or lowing of the platform
to make certain it was level.
Erecting the metal work
29. The puddled
iron (wrought iron)
structure of the
Eiffel Tower
weighs 7,300
tonnes, while the
entire structure,
including non-
metal
components, is
approximately
10,000 tonnes
Depending on the ambient
temperature, the top of the tower may
shift away from the sun by up to 18 cm
(7.1 in) because of thermal
expansion of the metal on the side
View from
below the tower
30. Three
lifts (North, East,
and West pillars )
will take you up to
the 1st and 2nd
floors (115m). To
visit the top floor
(276m), visitors
needs to change
lifts at 2nd floor
31. Maintenance of the tower includes
applying 50 to 60 tonnes (49 to 59 long
tons; 55 to 66 short tons) of paint
every seven years to protect it
from rust. The height of the Eiffel
Tower varies by 15 cm (5.9 in) due to
temperature.

Bastille Day is the name
given in English-speaking
countries to
the French National Day,
which is celebrated on 14
July each year
