Consider the five-story building shown in the figure.The average weights of the floor and roof are 100 Ib/ft2 and 70 Ib/ft², respectively. The values of Sps and Spjare equal to 0.9 g and 0.4 g, respectively. Since steel moment frames are used in the north-south direction to resist the seismic forces, the value of Requals 8. Compute the seismic base shear V. Then, distribute the base shear along the height of the building. 4 @ 25' = 100' Plan (a) гoof 20 |15 13 Building Section wind pressures in Ib/ft² (b) (c) The seismic base shear Vof the building is 285.8 kips.

Structural components of framed construction

It is a rigid and stable framework of structures that consists of structural members like slabs, beams, and columns that can resist the deformation due to the self-weight and high external loads and transfer the applied loads safely to the substructure and consecutively to the ground. It is made of different materials, such as reinforced concrete, steel, and wood. In ancient days, load-bearing structures were used to build houses and houses were built using load-bearing walls.
