摘要:
提出在主次梁交接处至支座处加设型钢，形成局部型钢混凝土(steelreinforcedconcrete，SRC)二次转换结构。采用有限元法研究不同剪跨比下局部SRC二次转换结构的抗剪、抗扭、缓解应力集中能力，并与SRC二次转换结构、钢筋混凝土(reinforcedconcrete，RC)二次转换结构进行受力性能比较。结果表明:局部SRC二次转换结构能明显缓解应力集中和扭转效应不利因素，当剪跨比为0.65~1.90时，其抗扭、抗剪效果最佳。
Abstract:
A secondary transfer structure was proposed, which added section steel at the junction of orthogonal and secondary beams to the bearing, making up local SRC secondary transfer structures. Finite element method (FEM) was used to study the shear resistance, torsion resistance and stress concentration relief ability of the local SRC secondary transfer structures under different shear span ratios. These mechanical properties were compared with those of SRC secondary transfer structures and reinforced concrete’s secondary transfer structures. Results show that local SRC secondary transfer structures can effectively relieve the stress concentration and the torsion effect, and their torsion resistance and shear resistance effects are the best when the shear span ratio falls in the range of 0.65~1.90.
