| 摘 要： | 在9个柱截面为三种典型异形柱(十字形、T形和L形) -板柱连接未配置抗冲切钢筋时的冲切特性试验基础上,以十字形柱-板柱连接为代表,通过三个配置抗冲切钢筋试件与三个未配抗冲切钢筋试件的对比试验,研究了异形柱-板柱连接配置抗冲切钢筋后的冲切特性,同时将锚栓和箍筋的抗冲切性能进行了对比。试验结果表明,抗冲切钢筋可以有效地提高板的受冲切承载力和延性,在改善延性方面,锚栓比箍筋更有效。另外,将国外几个主要规范ACI3 18、BS8110及MC90 ,关于对非矩形荷载面冲切临界截面周长的规定进行了比较,从试验结果看,ACI3 18规范的取法更合理。

| Abstract: | To investigate the characteristics of slab-column connections for nonrec tangula r columns,nine reinforced concrete slab-column connections for three typical sp ecially shaped columns(cross-shaped column,T-shaped column and L-shaped colum n) without shear reinforcement have been tested.Based on the test results,with t he cross-shaped columns as the representatives of the nonrectangular columns,th ree slab-column connections for cross-shaped columns with stud shear reinforce ments and stirrups were tested.Comparing with three similar specimens without sh ear reinforcement,the test results revealed that the shear reinfocement could en hance the strength and the ductility of the slab.Specifically the stud shear rei nforc ement is more efficientt than the stirrups.Besides,the test results verified tha t the provisions in ACI318 on the critical perimeter is more reasonable than tho se in European Codes. |
