The document discusses foundations and construction methods. It covers:
1) The purpose of foundations is to spread the load from the structure evenly over the subsoil and provide a stable, level base for building. Foundations must be strong enough to resist compressive forces from the structure above.
2) When constructing foundations or cavity walls, construction should start at the lowest level and wall ties should be used to reinforce cavity walls. Proper placement and spacing of wall ties is important.
3) Lintels over openings must be sized correctly to support loads without cracking. Concrete and steel lintels require minimum seating depths. Trusses need to be securely attached to wall plates and anchor straps help resist gable

EARTH RETAINING STRUCTURES & TYPES OF RETAINING WALL.pptxNaqeeb Khan Niazi
Earth retaining structures are built to retain a soil mass and create a difference in level between the ground surface located downstream and the ground surface located upstream of the structure, supported by the structure, usually to gain usable space.This is usually done by placing a fill behind the retaining structure (in elevation or embanking), or by extracting soil in front of the structure (in excavation or emptying), or by performing a combination of the two operations of emptying and embanking at the same time.

METHODS OF RETROFITTING EARTHQUAKE DAMAGESUmer Farooq
The primary purpose of earthquake retrofitting is to keep a home from being displaced from its concrete foundation. Retrofitting means making improvements to an existing building. The purpose is to make the building safer and less prone to major structural damage during an earthquake. Existing homes need to be retrofitted because our understanding of the effects of earthquakes as well as construction techniques have improved after the homes were built. The terms house bolting, foundation bolting and cripple wall bracing are often used synonymously with earthquake retrofitting

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.
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

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.

2. Loading on Parts of a Building
Foundation’s constructed as part of the
building or structure are termed ‘artificial’
foundation, the ground that they are laid
upon is classed as the ‘natural’
foundation.
3.
4. The purpose of a foundation is to spread the
load, from the structure above, over an
adequate bearing area of the subsoil, and
to provide a stable, level base on which to
build.
Although foundations are normally out of
sight, the effect of any movement of a
foundation is likely to be very noticeable in
the structure above.
Purpose of a Foundation
5. The foundation is sandwiched between the forces from the structure
and those from the ground thus subjecting it to compressive forces, so
the foundation must be constructed from a material that is strong
enough to resist any forces being imposed upon it.
8. When using Cavity walling below
ground
• A weak mix concrete is placed in the
cavity to resist Lateral thrust from ground
push.
• Use Ties or not?????
9. • A cavity wall consists of two slender walls If a
load is exerted to one or both of these slender
walls they may buckle or collapse under the
load. If the two leaves are tied together they
will virtually be as strong as a solid wall and
they can support more imposed loadings.
10. • A distance of 150mm max from the edge
of an opening (BR).
• A distance of 225mm max from the edge
of an opening (CoP).
• Vertically spaced at a maximum of 300mm
• 900mm max horizontally (or 750 if cavity is
75mm or more)
• 450mm vertically staggered
Position of wall ties
16. Opening in Walls
Any openings
(windows/doors) should be
a minimum of 675mm away
from any external corner of
a building.
17. Lintels
• The constructional member inserted into a wall
to support a load above an opening is called a
LINTEL.
• The imposed loads create stresses upon or
within any lintel, in particular at the top and at
the bottom, which may cause cracking and
failure. The size, shape and design of a lintel
must be such that it can overcome these
imposed stresses and loads.
21. RSJs USBs
must be sat on
a concrete
padstone (min
150mm) and
fixed by means
of rag bolts to
prevent tilt and
slip
22. Fixing Truss to Wall
• Wall plate – Pan bedded
on to ensure level and
parallel
• Fastened to block-work
by Galvanised steel
straps screwed to wall
and wooden Pan set at a
max 1800mm
• Help spread load of roof
through wall on to
foundations
23. • Clip used for fixing truss to wall plate
• Screw
Truss clip
24. Anchor Straps
• Anchor Strap should
fix to at least three
trusses and bed into
block-work this helps
with the roof
structure resisting
the pull of the gable
25. Anchor Straps in Roof construction
• These anchor
ties should be
screwed not
nailed
27. External Stability
• Piers
Height should not exceed
8 times its minimum dimension
ie: what would be the height of a free standing pier
if it measured 400mmx400mm
28. The purpose of an attached pier is
to :-
• Provide the wall with additional strength to
counter against lateral pressure.
• Accommodate loading and transfer this
load to the walling.
29. Attached piers
• Building Regulations state slender walls should
be supported at corners and at intermediate
lengths i.e. garages conservatories
• Maximum distance between piers =
Every 3m
