Post tension slab is a combination of conventional slab reinforcement and additional protruding high-strength steel tendons, which are consequently subjected to tension after the concrete has set. This hybridisation helps achieve the formation of a much thinner slab ...
Modulus of rupture is a measure of the tensile strength of concrete beams or slabs. Flexural strength identifies the amount of stress and force an unreinforced concrete slab, beam or other structure can withstand such that it resists any bending ...
Construction of concrete stairs includes steps such as designing, preparing foundation, building formwork, placement of reinforcement steel bars, concreting, finishing and curing. Construction of concrete stairs is a difficult task that requires an engineer to study all the aspects and design ...
Construction joint is placed when the mass concreting works are done and cannot be completed on a single stretch. The interface of the past day's hard concrete and present days fresh concrete is to be properly done so as the ...
Construction of concrete walls is a crucial phase in building construction. It is constructed as a load bearing structure to transfers loads from floor to the wall below or to the foundation, in addition to divide spaces in multi-storey buildings. ...
Bar bending schedule (BBS) of an concrete footing provides the reinforcement details and the total steel quantity required for the footing construction. The BBS and quantity of steel reinforcement required for a simply isolated footing are calculated and explained by ...
The trapezoidal footing formula is used to determine the volume of a trapezoidal footing from the respective drawing specifications. Here, the trapezoidal footing formula is explained and clarified with the help of an example. Trapezoidal Footing Formula As shown in figure-1 below, ...
