【摘要】 通过对3个非等壁厚矩形钢管混凝土纯弯构件的试验研究,考察非等壁厚矩形钢管混凝土受弯构件的力学性能。试验结果表明,非等壁厚矩形钢管混凝土受弯构件具有良好的延性和后期承载力,其抗弯性能优于同等条件用钢量的等壁厚矩形钢管混凝土构件。所得结论可供有关工程设计和理论研究参考。更多还原

【Abstract】 Tests on three non-uni-thickness walled rectangular CFT(concrete-filled steel tube) members subjected to pure bending are carried out.The mechanical behavior of the member is studied.The experimental results show that non-uni-thickness walled rectangular CFT members subjected to pure bending have good ductility and high bearing capacity.The bearing capacity of non-uni-thickness walled rectangular CFT members subjected to pure bending is prior to uni-thickness walled rectangular CFT members under the same steel-ratio condition.The conclusions can be a reference for the design and the theory study of non-uni-thickness walled rectangular CFT members.更多还原
