    Abstract

    A new design method named the Partial Capacity Design Method (PCDM) has been proposed by the Authors. In this method insteas of sise sway mechanism, partial side sway mechanism is employed, in which for a certain seismic load level (named target seismic load) some columns are allowed to develop plastic hinges while some selected columns are to remain elastic except at the base. To ensure these selected columns remain elastic, these columns are designed to resist magnified internal forces. The internal forces due to the nominal seismic load are multiplied by a certain magnification factor, f. The performance of several symmetrical fully ductile concrete moment resisting frame designed in accordance with the latest Indonesian Seismic Code (SNI 03 1726-2002) using the proposed method has been presented elsewhere. In this paper the proposed method (PCDM) is used to design structures with vertical set-back. The seismic performances of the structures are evaluated using dynamic non-linear time history analysis. The results show that under the intended seismic load level (target seismic load), the selected columns remain elastic as expected. The structures performed very well in accordance to the criteria suggested in the Asian Concrete Model Code (ACMC), however one should be very careful not to overdesign the beams connecting to the selected columns.
