摘要: 就复合材料包覆混凝土梁及其框架结构的动力响应分析进行了初步的理论和应用研究.具体是采用非经典理论推导出碳纤维包覆混凝土复合梁的抗弯、抗剪刚度,然后结合ANSYS软件进行FRP-RC结构有限元动力响应分析.以单根梁及单层单跨框架为算例,与ANSYS三维实体单元的计算结果进行了比较,结果表明本文方法简便易行,且精度高,速度快.Abstract: A theoretical analysis of the dynamic response of FRP-RC beam and frame structures is performed in this paper. Bending and shear stiffness of carbon fiber wrapping concrete beams are obtained from the non-classical theory. ANSYS software is used to analyze the dynamic response of the structures. A single beam and a single-layer and single-span frame are taken as examples and the results are compared to those obtained from ANSYS 3D analysis. It is clearly demonstrated that the method used in the present research is much more convenient and highly efficient.
