中文摘要：

通过15个带栓钉连接件的型钢混凝土短柱在单调荷载下的推出试验及1个自然黏结试件的对比试验，研究带栓钉连接件型钢混凝土短柱的破坏形态、裂缝模式、荷载一滑移特性、型钢应变分布、剪力传递承载力等。试验结果表明：带栓钉连接件型钢混凝土推出试件的破坏以混凝土劈裂为主，劈裂裂缝出现的方位与栓钉的布置位置有关。典型试件的荷载．滑移曲线大致可分为5个阶段，分别为无滑移段、滑移段、破坏段、荷载下降段及残余段。由于栓钉剪切变形的影响，栓钉根部混凝土受局部承压作用，混凝土与型钢表面原有的自然黏结将受到损坏，近栓钉位置的型钢应变产生突变，应变分布表现出与自然黏结试件不一样的特征。在其他条件基本相同的情况下，型钢腹板布置栓钉的试件，其极限荷载和残余荷载比型钢翼缘布置栓钉的试件高，与极限荷载相对应的端部滑移比型钢翼缘布置栓钉的试件大。根据试件的受力机理和力的扩散原则，提出了带栓钉连接件型钢混凝土推出试件的承载力计算公式及防止栓钉外侧混凝土劈裂破坏的构造措施，公式计算结果与试验结果总体相符且偏于安全。

英文摘要：

Fifty steel reinforced concrete （SRC） short columns with stud connectors and one comparative steel reinforced concrete short columns without stud connectors on the surface of shape steel were statically tested to study the fhilure pattern, crack mode, load-slip characteristics, steel strain distribution and shear force transmission capacity of steel reinforced concrete specimens with stud connectors. Test results show that the main failure pattern of steel reinforced concrete short columns with stud connectors is concrete split failure, and the position of the split cracks is related to the location of stud connectors. Typical load-slip curve of specimens can be divided into five stages, including no slip stage, slip stage, destruction stage, load decline stage and residual load stage. Due to the deformation of stud connectors, the concrete in the roots of stud are under local pressure, leading to strain mutation of steel near the stud and the damage of the original natural bonding between concrete and steel. Compared with the specimens with studs at the steel flange, the limit loads and residual loads of the specimens with studs at the steel web are much higher, and the end slips of the specimens with studs at the steel web are much larger. According to the load mechanism and force spread principles of the specimens, the force transfer calculation formula and structural measures to prevent the split of concrete beside the stud are put forward. The calculation results by the formula generally agree with the test results to a safe extent.
