摘要/Abstract

摘要： 由于场地限制和建筑物功能的需要，地震区所建的高层建筑往往难以满足我国现行抗震规范关于“平、立面宜规则对称”的要求，防震缝的设置不可避免。深入研讨了合理的防震缝宽度以及简便、实用的防震缝宽度的确定方法。针对我国现行抗震设计规范，对防震缝最小宽度的规定进行了讨论，建议改变传统的防震缝最小宽度的确定方法，宜采用顶点位移法来确定防震缝的最小宽度。

Abstract: Because of the limit of field and the need of buildings function, the high buildings in the earthquake area can not meet the criterion that “the plane and frontispiece of seismic buildings should be regular symmetrically”, so it is unavoidable to set seismic joint. How to set seismic joint suitably and how to adopt simple or practical methods for determining seismi
c joint width were deeply studied. The paper discusses the current seismic criterion about the least width of seismic joint and advises to change the conventional methods of setting the least width of seismic joint; moreover, designers can adopt the apical displacement method to decide the least width of seismic joint.
