A procedure for damage-based seismic design of moment frame structures

A new method for seismic design of structures with the aim controlling earthquake damage to a prescribed level is presented in this paper. The specified special moment frame buildings vertical and horizontal regularity. main idea determining story drift correlation selected index value. For purpose, Park-Ang correlated maximum drift. Through performing several nonlinear dynamic analyses steel regression analysis, it shown that such possible studied building type by simple linear relation. Beginning from desired value index, calculated using developed equation same are designed displacement-base procedure. Results analysis show under suit spectrum compatible ground motions consistent initial proposed
