为了保证钢管混凝土梁柱节点剪力的可靠传递，常需在钢管内设置抗剪连接件。抗剪连接件的承载能力与其下混凝土的局部承压强度有关，为此，本文进行了２１个钢管混凝土在界面附近的局部承压试验，局压垫板形状分为环形和花瓣状条形，以模拟环形和钉形抗剪连接件。根据试验结果，探讨了钢管混凝土界面附近局部承压的工作机理，并给出了计算公式。
In order to ensure the reliable transmission of the shear force of steel pipe concrete beam-column joints, it is often necessary to provide shear connectors in the steel pipe. The bearing capacity of shear connectors is related to the local compressive strength of the concrete underneath. For this reason, the local pressure bearing tests of 21 concrete-filled steel tubes near the interface are carried out. The shape of the local pressure plate is divided into a ring shape and a petal shape. To simulate ring and spike shear connectors. According to the test results, the working mechanism of local pressure bearing near the concrete-filled steel tube interface is discussed, and the calculation formula is given.
