新型组合连梁的基本动力特性研究

Basic dynamic performance study of coupling beams structure system

对分别采用钢筋混凝土连梁、钢连梁与新型组合连梁的高层建筑结构进行对比,采用ANSYS软件建立试验模型,进行模拟试验,研究新型组合连梁对结构动力性能-自振频率的影响.结果表明,在高层建筑中,采用新型组合连梁较采用钢连梁结构方案,其自振频率高,改善了核心筒体即连肢剪力墙的工作性能.

To study the dynamic behavior of a new type of composite coupling beam under elastic stage, tests of model with a traditional reinforced concrete coupling beams, a steel coupling beams and a new type of composite coupling beams were carried out. Test models were established firstly with the software of computer simulation analysis -ANSYS. The effect of the coupling beams on elastic stage of the structural system was examined to test vibrating frequency of model. The experimental results showed that the high buildings with coupling beams had good dynamic performance ff the composite coupling beams with control devices were installed on the middle floors of the structural system.
