Relatively comprehensive test study on the strength capacity of the reinforced concrete beam under bending moment, shear force and axial tensile force was carried out.

对弯、剪、轴拉复合受力状态下钢筋混凝土梁的承载能力进行试验研究。

Based on the test results and analysis, restoring force model of composite steel concrete beam was established with consideration of the degree of shear connection.

在试验研究的基础上，考虑了剪力连接程度的影响，建立了钢—混凝土组合梁的恢复力模型，并编制了相应的计算程序。

Test results indicate that effective cooperation can be achieved by the shear-resistant connection between the reinforcement in the negative moment area and the outer-plated steel beam.

试验表明，外包钢-混凝土组合梁负弯矩区钢筋和外包钢梁通过抗剪连接措施能有效地共同工作；
