THE STRUCTURAL PERFORMANCE OF TOWER CRANES USING COMPUTER PROGRAM SAP2000-v18

Abstract

In this research, three configurations of tower cranes were taken to study the structural performance of them by using Structural Analysis Program SAP2000. Different load cases were considered as followed: dead, live and wind loads and their combinations. The analysis results were presented in graphical forms in order to study the structural performance of the three configurations (tower crane type 1, 2 and 3). It was taken the variation of axial forces and displacements with height of tower crane, and variation of axial forces and deflections on jib’s arm. The design of tower cranes components is done using Allowable Stress Design (ASD) according to American Institute for Steel Construction (AISC). From the variation of axial forces, displacement in x- and y- directions, deflection on jib’s arm. It was noticed that tower crane (1) is have best configuration in comparison with the other two tower cranes (2) and (3).
