Abstract

A Direct Displacement Based Design (DDBD) methodology is validated for concentrically braced frame (CBF) systems. CBFs are widely used as the lateral resistance systems because they overcome many limitations in other resistance systems. The validity of the method is assessed by designing four and twelve-storey CBF buildings, in which the performance is checked using nonlinear time history analysis (NLTHA) employing eight different accelerograms with displacement response spectra matching the design displacement spectrum. The results show that the displacements and drifts obtained from NLTHA are falling within the design displacement limits used in the DDBD procedure. However, the results are found to be conservative when assuming no contribution to the lateral resistance by compression members.
