| 中文摘要: |
| 混凝土叠合连续梁由于其特殊的使用性能在实际工程中具有实用意义,利用大型通用有限元软件ANSYS模拟一组叠合连续梁和对比梁,通过对比发现叠合连续梁在跨中截面存在受拉钢筋应力超前和后浇层受压区混凝土应力滞后以及支座负弯矩处受拉钢筋应力滞后等现象,为实际工程中的设计和施工提供了理论依据,使其更能广泛的应用。 |
| 英文摘要: |
| Due to its special using properties，practical significance in the actual project was given in concrete composite continuous beam. In this paper，the large general一purpose finite element software ANSYS was used to simulate a couple of composite continuous beam and contrast beam. By comparing the two，in midspan section，the phenomenon of tensile reinforcement stress ahead and after pouring layer compression none of concrete stress lag was existed，in the bearings negative moment，the phe-nomenon of tensile reinforcement stress hysteresis was showed. Theoretical basis was offered for the de-sign and construction of actual engineering, and make the composite continuous beam more widely used. |
