Structural Seperation of Unsymmetric Highrise Apartments

It is well known that the symmetric buildings have higher resistance than the unaymetric ones do under seismic load. However, it is sometimes inevitable to build an unsymmetric structure due to the site conditions or architectural needs. The unsymmetric building has structural disadvantages under seismic load. In such a case the structural seperation joints are often used to avoid those disadvantages. This paper presents a method to determine the width of the seperation joints for unsymmetric, reinforced concrete apartments structured by walls and slabs only. The variables of the study were the ratio of shear-wall stiffness to the building length in the same directron, the building height and the story mass.
