STUDY ON STRUCTURAL COMPUTATIVE PROGRAMS BY 'BENCHMARK STRUCTURE' CALCULATION : Part 2 The secondary design

Abstract

In order to grasp the present circumstances and problems of computer utilized structural calculation, we applied very small and simple building models we call 'benchmark structures' to various structural computative programs actually used in various companies. Subsequently we studied the difference among their calculated results quantitatively and investigated the reason of each numerical difference. Our studies for the primary design have been reported in the previous paper, so this paper describes the studies for the calculation of horizontal load-carrying capacity and structural characteristics factor (D_s) in the secondary design. Here we also comfirmed conspicuous difference among the calculated results.
