摘　　要：分析了弯剪作用下预埋件与后锚固两种锚固方式的设计特点,通过一个工程算例的计算结果比较可知,后锚固设计中当考虑全部锚筋参与受剪时,可充分发挥锚筋强度,而且与预埋件设计结果具有可比性。预埋件设计较全面地考虑了多种因素对承载力的影响,对后锚固连接设计有借鉴意义。Design methods of two types of steel-to-concrete connections under combinations of moment and shear loading,cast-in-place anchorage and post-installed anchorage,are discussed.The calculation results of an example are used to draw the conclusion that in post-installed anchorage design steel reinforcements could develop their full strength with the assumption that all bonded-in reinforcements take up shear loads and the two types of anchorage connections have comparable results.In design method of cast-in-place reduction factors that effect the strength have been included,which give good advice to post-installed anchorage design.
