摘要
本文对钢-混凝土高托座组合梁的挠度进行了理论分析及试验验证,分析中考虑钢梁与混凝土之间的滑移及混凝土的非线性对挠度的影响,通过试验验证,计算值与实测值吻合良好。
Theoretical analysis and experimental studies are made for the steel and concrete high haunched composite beams. The Slips between steel-concrete and the affect of concrete nonlinear on composite beams deflection are considered. The test data of three full-scale test beams show that the calculation results from the mothod of this paper are quite coincided with the tests ones. Therefore, the revised formula put out in this paper is adoptable for practical design purposes.
