板内配筋参与梁整体工作和梁端延性设计

Working Together both the Reinforce ment in Slab and Beam and Ductility Design at the End of Beam

文章分析了现浇梁板梁两侧板筋参与梁整体工作的机理以及设计中考虑梁两侧板筋作用对梁端延性的改善情况,计算表明考虑板筋作用可使梁端的延性系数增大9%～21%。

The working mechanism both the reinforces in the slabs beside beam and the beam in the in-situ beam-slab,and the advantage of the ductility at the end of beam considering the reinforces in the slabs beside beam are analyzed.It makes the ductility coefficient at the end of beam increase 9%～21% to consider the reinforces in the slab。
