| Abstract: | This paper points out that the main design principles of an asymmetrical building subject to horizontal earthquake are to take into consideration of (1) the torsional angle of the floor (rigid diaphragm) not to induce torsion exceeding the allowable, (2) the inter-story displacement at utmost end frame or shear wall should be less than that required by design code, (3) stresses in plane of the slab shall be controlled within acceptable extent under different intensity earthquakes. Current seismic design code only utilizes the torsional displacement ratio to control the floor torsion. This seems not reasonable enough since its definition is the multiple of the floor torsional angle and the distance of floor mass center till the utmost end frame or shear wall. The International Mayor Building of Shenzhen City is 26 storied high, the tower is L-Shaped in plan and with a transfer beam-slab system at 9th floor. The earthquake action will induce evident torsion to the structure. This paper introduces the seismic design considerations of the building. | |
