| 摘 要： | 通过一组纵、横向布置筒芯的现浇混凝土空心板荷载试验,研究了该空心板抗弯承载力、裂缝分布与发展、变形及破坏形态等。试验结果表明:纵、横向布置筒芯的现浇混凝土空心板的抗弯刚度、抗弯承载力和破坏形态非常相似,筒芯的布置方式对现浇混凝土空心板的受弯性能没有明显影响;利用现行规范计算其开裂弯矩和极限弯矩是偏于安全的。

| Abstract: | The cast-in-situ concrete hollow slabs laying longitudinal and transverse tube filler were tested.The capacity of bending,crack,deflection and failure model were studied.Test results show that the bending rigidity,the capacity of bending and the failure model of the cast-in-situ concrete hollow slabs laying longitudinal and transverse tube filler are very similar.The mode of laying tube filler has almost no influence on the bending behavior.It is safe to use current code to calculate the crack bending moment and ultimate bending moment. |
