摘要
介绍了后锚固群锚连接在拉剪复合受力情况下承载力计算的两种方法:弹性方法和塑性方法。弹性方法简单实用,而且偏于安全,已被广泛认可;塑性方法目前研究的较少,文中仅针对锚栓钢材受拉破坏的情况,分别对破坏由拉力控制和拉剪控制情况下锚栓中的内力分布以及极限承载力进行了初步探讨。
Two methods-elastic approach and plastic approach-for calculating the resistance capability of post-installed multiple-anchor connections under combinations of tension and shear loads are presented. The capacity predicted using elastic approach which is simple and practical is conservative theoretically and the approach is accepted widely, while little research result about the plastic approach has been shown. Based on plastic approach, the behavior and design of multiple-anchor connections that failure is controlled by the strength of anchor steel is addressed, distribution of load among the anchors and ultimate capacity of connections for which strength is controlled by tension and tension-shear separately are discussed.
