Two simplified adaptive load patterns for conservative estimation of seismic demand in 2D frames by pushover analysis are presented. The influence of load pattern in assessment of target displacement and distribution of demand along the height of the structure is investigated by comparing results of non linear history analysis, and non linear static analysis for eccentric braced frames. Numerical analyses show that the proposed load patterns provide safe estimation of the seismic response more accurately than load patterns proposed by seismic code.

Abstract
Two simplified adaptive load patterns for conservative estimation of seismic demand in 2D frames by pushover analysis are presented. The influence of load pattern in assessment of target displacement and distribution of demand along the height of the structure is investigated by comparing results of non linear history analysis, and non linear static analysis for eccentric braced frames. Numerical analyses show that the proposed load patterns provide safe estimation of the seismic response more accurately than load patterns proposed by seismic code.
