performance assessment of different tabular systems for tall buildings against wind and earthquake effects

Structural system selection for tall buildings against lateral wind and earthquake loads is of great importance in view of minimum material use and structural weight. structural systems, for tall buildings, have been classified into four main groups, namely rigid frames, shear walls, combined wall-frame structures and tube systems (kheyroddin et al., 2012). in the tube system category, tube in tube (tit), braced bundled tube (bbt) and bundled tube (bt) are the most popular structural configurations in order to reduce the shear lag in tall buildings (taranath, 2010). number of studies has been conducted to compare various lateral-resisting systems in tall buildings against wind and earthquake effects (kakde et al., 2017; mulla & srinivas, 2015).
