Abstract
Lateral load can be considered to be those which act parallel to the ground plane and may occur at
many angles other than perfectly horizontal generally considered to act transversally to the primary
structural system. And the seismic building codes are used in analysis because of to protect human
life, to limit damage, to keep the structural safety of buildings and etc.
Although this lateral load distribution is significant in buildings in our country there is no sufficient
research on the assessment of the effects of equivalent lateral force distribution by using different
international codes.
Then this thesis works provides an investigation of the back ground of different provisions that are
specified by different international codes.
And in addition this thesis work studies the effects of lateral force distribution on the seismic
performances of the structures like lateral distribution of force, story shear, period and etc by using
different codes.
The provision codes selected for the current issues are like IBC 2009, EC8, 2004 and other
international building codes. By using this code provisions lateral force distribution and story shear
of different codes will be compared with respect to RSA.
