| 摘要: |
| 通过受集中荷载作用下钢筋砼五跨连续板的试验，研究了横向拼缝对板的整体性影响；在不同位置荷载作用下板的裂缝形成、发展及最终破坏形态；板的开裂及破坏荷载；以及单向板的应力状态。试验中采用的横向拼缝措施，能够保证板的整体性。由于集中荷载局部效应的影响，单向板中也存在双向应力状态，并使板产生横向裂缝。 |

| Abstract: |
| By strength tests of RC continuous slab under concentrated loads, the innuences of transverse assembling seam upon global property of slab; the formation, development and final failure pattern of cracks under loads acting at different positions; the cracking and failure loads of slab and the stress state of one - way slab were studied in this paper. The transverse assembling seam measures adopted in tests can guarantee the globality of slab.Because of the innuences of local effect of concentrated loads, there also exists two - way stress state in one - way slab and causes transverse cracks. |
