扭矩作用下圆心角对钢筋混凝土曲梁性能影响研究

Reseach on the effect of central angle on the performance of reinforeed concrete curved beams under torque

为了进一步研究扭矩作用下圆心角对矩形截面钢筋混凝土曲梁结构性能的影响,以10片不同圆心角钢筋混凝土曲梁试件为研究对象,通过有限元仿真计算。研究结果可作为矩形截面钢筋混凝土曲梁力学性能研究的有益补充,亦可为钢筋混凝土曲梁的发展和应用提供一定借鉴。

In order to further study the effect of the central angle on the structural performance of the rectangular section reinforced concrete curved beam under the action of torque,10 pieces of reinforced concrete curved beam with different central angles were taken as the research object,and the influence of the central angle on the plastic deformation,torsional stiffness and ultimate bearing capacity of the rectangular section reinforced concrete curved beam was analyzed by finite element simulation.The research results can be used as a useful supplement for the study of mechanical properties of RC curved beams with rectangular section,and can also provide some reference for the development and application of RC curved beams.
