Let us talk about Seismic Retrofitting today. Retrofitting can be broadly classified into Conventional methods and non-conventional methods Conventional Methods are methodologies adopted to increase the strength of structure either globally or locally. Non-Conventional Methods are methodologies adopted reduce seismic force into the system. All the methods can be suitably…
How does one obtain design strength of concrete = 0.45fck as given in IS456:2000??? Here is the explanation: In india, we test concrete cubes to determine 28-days characteristic strength of concrete, which is depicted by “fck” However, we all know that, if we cast cylinder from the same concrete mix,…
One of the major design challenges when we design a Post-Tensioned transfer slab, is to consider the sequence of construction, so it’s required to stress the tendons in stages until reaching its final force. The question here, which approach is more reliable and can be considered in compatibility with the…
A structure is called stable if for any given force it has a load path to ground it to support(foundation) without yielding an infinite deformation. [1] Stability is a general term that is referred for lateral forces and the stability system is referred to as a lateral load resisting system.…
few important points in this image – There is no shear wall along the other orthogonal direction. Then, how the base shear will be carried by the shear walls in that direction? If this is a dual system, the shear walls need to carry most of the base shears and…
