组合框架梁的试验与分析

EXPERIMENT AND ANALYSIS OF COMPOSITE FRAME BEAM

组合框架梁由于梁端存在负弯矩区,其设计及构造较简支组合梁复杂,限制了其在实际工程中的应用。针对一新型组合框架梁模型在住宅钢结构实际工程中的应用进行试验研究,结果表明,该组合框架梁模型应用于实际工程中是安全适用的,设计计算结果与试验数据比较偏于安全。

In negative moment region of composite frame beam, its design and the detail of struction are more complicated than that of simply supported composite beam, so it was seldom adopted in project. The test on a new-type composite frame beam is introduced. The testing results show that the composite frame beam is secure and reliable when adopted in the steel structure of residence. The design calculating values is conservative compared with those of the test.
