Raft foundations are used when buildings have heavy loads, compressible soil, or require minimal differential settlement. A raft foundation is a continuous concrete slab that supports all building columns. It can be designed using either a rigid or flexible approach. The rigid approach assumes the raft bridges soil variations, while the flexible approach models soil-structure interaction. Key considerations for raft design include bearing capacity, settlement, stress distribution, and structural component sizing.
This document discusses the need for raft foundations. Raft foundations are recommended when:
1) Building loads are heavy or soil capacity is low, so individual footings would cover too much area.
2) Soil contains weak lenses or cavities, making differential settlement hard to predict.
3) Structures are sensitive to differential settlement.
4) Structures like silos naturally suit raft foundations.
5) Floating foundations are needed over very weak soil.
6) Buildings require basements or underground pits.
7) Individual footings would experience large bending stresses.
Raft foundations increase capacity, decrease settlement, and equalize differential settlement compared to individual footings. However,

For each structure, the equations relating slope and moment are written for each member. The slopes and moments are then solved for using these equations along with the boundary conditions of zero rotation and moment at supports. The final moments calculated at each point are provided at the end.
Shallow foundations are foundations with small depths limited to the width of the footing. They spread loads from the superstructure over a larger area of soil to reduce stress intensity to a level the soil can safely support. Shallow foundations are classified as isolated or combined footings. Isolated footings support single walls or columns, while combined footings support two or more columns and come in shapes like rectangular, trapezoidal, or T-shaped. Mat foundations are used for soils with very low bearing capacity, forming a single, continuous raft to support the entire structure.
Shallow foundation(by indrajit mitra)01Indrajit Ind
Shallow foundations transmit structural loads to near-surface soils and are used when the upper soil layer is sufficiently strong. They include spread, combined, strap, and raft foundations. Design considers factors like bearing capacity, settlement, and water table effects. Plate load tests determine ultimate capacity and settlement by measuring pressure-displacement curves. Terzaghi's theory and IS codes provide design guidance.
The document describes different types of shallow foundations, including spread footings, combined footings, and raft/mat foundations. Spread footings include wall footings, reinforced concrete footings, inverted arch footings, and column footings. Combined footings are used when columns are close together or near a property line. Raft foundations consist of a thick concrete slab covering the entire structure area and are used when soil capacity is low or loads are large. The document also discusses advantages, limitations, and construction procedures of shallow foundations.
1. Superstructure construction includes column, beam, floor, wall and roof located above ground level. Materials used are timber, steel and concrete.
2. Timber floor construction involves plank wood supported by timber joists and beams. Reinforced concrete uses column and beam construction with formwork, steel bar installation and concrete pouring.
3. Load bearing walls support loads and transfer to foundation, with minimum thickness of one brick. Non-load bearing walls only support own weight and are half brick thickness.
Shallow foundations are foundations where the depth is equal to or less than the width. There are four main types of shallow foundations: 1) Spread footings which spread loads over a larger area and are used for light loads or strong soils, 2) Combined footings which are preferred when columns are close together to make construction more economical, 3) Strap or cantilever footings which connect independent footings with a beam that does not transfer pressure to the soil, and 4) Mat or raft foundations which cover the entire area beneath a structure and are used for supporting loads on soft soils by spreading them over a large area.

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
High-Volume Fly Ash Concrete: According to some researchers, more than 30% fly ash by mass (equivalent as 50% by volume) of the cementitious material may be considered enough to classify the mixtures as High-Volume Fly Ash (HVFA) concrete. It is possible to produce sustainable, high performance concrete mixtures with 50% or more cement replacement by fly ash.
Diaphragm wall: Construction and DesignUmer Farooq
The document discusses diaphragm walls, which are concrete or reinforced concrete walls constructed below ground using a slurry-supported trench method. Diaphragm walls can reach depths of 150 meters and widths of 0.5-1.5 meters. They are constructed using tremie installation or pre-cast concrete panels. Diaphragm walls are suitable for urban construction due to their quiet installation and lack of vibration. The document discusses different types of diaphragm walls based on materials and functions, and provides details on their design, construction process, and material requirements.
One of the most efficient structural systems against heavy wind loads is the bundled tube structural system
The first person to implement the bundled tube structural system was Fazlur Rahman Khan from Dhaka, Bangladesh with the design of the DeWitt-Chestnut Apartments in Chicago, Illinois.
Reinforced earth is a combination of earth and linear reinforcing strips that are capable of bearing large tensile stresses.
The reinforcement provided by these strips enable the mass to resist the tension in a way which the earth alone could not. The source of this resistance to tension is the internal friction of soil, because the stresses that are created within the mass are transferred from soil to the reinforcement strips by friction.
MECHANICAL PROPERTIES OF HIGH VOLUME FLY ASH CONCRETE SUBJECTED TO ELEVATED ...Umer Farooq

THE SACRIFICE HOW PRO-PALESTINE PROTESTS STUDENTS ARE SACRIFICING TO CHANGE T...indexPub
The recent surge in pro-Palestine student activism has prompted significant responses from universities, ranging from negotiations and divestment commitments to increased transparency about investments in companies supporting the war on Gaza. This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.
