| 摘 要： | 对5根部分充填混凝土-钢箱连续组合梁进行静力加载试验,研究组合梁在负弯矩作用下的混凝土面板的裂缝开裂和发展特征.根据试验结果与理论分析,综合考虑力比、栓钉间距对部分充填混凝土-钢箱连续组合梁裂缝特征的影响,对比负弯矩区裂缝宽度试验值与各文献计算值.结果表明:力比对裂缝最大宽度的影响较大,栓钉可引起次生裂缝的产生,故应将力比及栓钉连接件的间距作为部分充填混凝土-钢箱组合梁中支座区最大裂缝宽度计算的重要参数.

| Abstract: | Static loading tests were carried out on 5 partially filled concrete-steel continuous composite beams to study the cracking and development characteristics of cracks under the action of composite beams negative bending moment. According to the test results and theoretical analysis, the effects of force ratio and stud spacing on the crack characteristics of partially filled concrete-steel box continuous composite beams were comprehensively considered, and the experimental value of the crack width in the negative bending moment area was compared with the calculated value of various literatures. The results show that the force ratio greatly influences on the maximum cracks width; and studs can cause secondary cracks. The force ratio and the stud spacing should be taken as important parameters for calculating the maximum crack width in the bearing area of partially filled concrete-steel box composite beams. |
