| 摘 要： | 型钢混凝土(SRC)结构由于其良好的受力性能以及在地震中表现出来的优良延性,已被越来越多地应用在工程实践中。为了进一步了解其受力性能,针对不同混凝土强度等级、受拉钢筋配筋率、受拉钢筋保护层厚度、型钢保护层厚度对SRC梁刚度的影响,对6根SRC梁进行了受力全过程载荷试验;结论表明提高混凝土强度等级与纵筋配筋率可以增强SRC梁的抗弯性能,而增大保护层厚度则相反。

| 关 键 词： | 型钢混凝土 梁 抗弯性能 延性 |

| Abstract: | SRC structure has been increasingly applied in practical engineering because its favorable flexural behavior and eminent ductility exhibiting in seism.To further comprehend their mechanical behavior,the author had done loading experiments of six SRC beams with different concrete intensity grades,ratio of bars,cover thickness of bars,and section steel.In conclusion,increase of concrete intensity grades and ratio of bars can enhance their rigidity behavior,but increases of cover thickness educes contrary result. |
