The AASHTO LRFD Bridge Design Specifications are intended for use in the design, evaluation, and rehabilitation of bridges. The specifications employ the Load and Resistance Factor Design (LRFD) methodology, using factors developed from current statistical knowledge of loads and structural performance

Thickness of concrete slab depends on loads and size of the slab. In general, 6 inch (150mm) slab thickness is considered for residential and commercial buildings with reinforcement details as per design. Methods used for finding slab thickness varies for different types of slabs.

An isolated footing is one of the most used types of foundation to support single-columns when they are arranged at a long distance. An isolated footing must be designed to avoid exceeding its bearing capacity and provide safety against overturning or sliding while preventing the ground from settling.

Footings are an important part of foundation construction. They are typically made of concrete with rebar reinforcement that has been poured into an excavated trench. The purpose of footings is to support the foundation and prevent settling. Footings are especially important in areas with troublesome soils.
FOOTING DESIGN PROGRAMME USING LIMIT STATE METHOD Read More »
“FOOTINGS” is a spreadsheet program written in MS-Excel for the purpose of analysis of rigid rectangularspread footings with up to 8 total piers, and for either uniaxial or biaxial resultant eccentricities. Overturningsliding, and uplift stability checks are made when applicable, and resulting gross soil bearing pressures atthe four (4) corners of the footing are calculated.

A rectangular tank, reaching from floor to ceiling, is relatively expensive to construct as it has to be designed to cope with quite large hydraulic pressures, so there is an advantage in using vertical cylindrical stores, which are placed behind the double glazing as in the Trombe wall system.

Pile behaves as a transversely loaded beam in case of lateral loads and they transfer lateral load to surrounding soil by means of lateral resistance of the soil. Pile shifts horizontally in response to applied load which results in bending, rotation or translation of pile.

It is also known as the bearing capacity of piles. … Pile load capacity calculation is done for single pile or a group of piles based on the requirement of number of piles for the given load or size of foundation.

A raft foundation, also called a mat foundation, is essentially a continuous slab resting on the soil that extends over the entire footprint of the building, thereby supporting the building and transferring its weight to the ground. … This reduces the stress on the soil.

Mat foundations also are known as raft foundations, is a thick concrete slab placed on the ground as the foundation of the structure. … With the increase of the axial loads on the structure or due to the poor ground conditions, the area of the footings (isolated, combined, strip footing, etc) need to be increased.

Strap footings or cantilever footings are a special form of combined footings. They consist of two separate bases that are connected (balanced) by a strap beam. In the design of strap footing, it is assumed that the strap beam is rigid and does not transfer any load by bearing on the soil at its bottom contact
