    Assessment of the Effects of Equivalent Lateral Forces by Using Different International Building Codes.
    (Addis Ababa University, 2014) Yimer, Amelework; Zekaria, Adil (PhD)
    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.
