摘要
对埋置于混凝土中的膨胀型建筑锚栓进行拉拔试验,利用弹性理论对混凝土体内受集中力作用时的应力状态进行弹性分析,结合修正的莫尔库仑材料破坏准则确定了锚栓在轴向拉拔力作用下的弹性极限荷载。
In this article,the expansion building anchors embedded in the concrete and subjected to the concentrated tension load are tested.By using elastic theory,the elastic stress condition with a concentrated tensile force in concrete body have been got.We have also got elastic ultimate load and pull-out capacity of the expansion anchors by using Modified Coulomb material failure criterion and ultimate equation.
