【摘要】 通过对6根方钢管自密实混凝土纯弯试件的试验研究,考察了方钢管自密实混凝土的纯弯力学性能。采用数值计算的方法对方钢管自密实混凝土纯弯试件进行了受力全过程分析,并和实验结果进行了对比。最后将设计规程ACI(1999),AISC-LRFD(1999),AIJ(1997),BS5400(1979)和DBJ13-51-2003(2003)对抗弯承载力和抗弯刚度的计算结果与方钢管自密实混凝土试验结果进行了对比。更多还原

【Abstract】 Six self-compacting concrete-filled square steel tubes subjected to pure bending were carried out in this paper. The results show that self-compacting concrete-filled square steel tubes subjected to pure bending have high bearing capacity, excellent rigidity and good ductility. The behavior of the members is studied. Numerical analysis method applied for the analysis of flexural behavior of self-compacting concrete-filled square steel tubes subjected to pure bending. The analytical results are compared with those of tests. Finally, the difference of the calculation of the bearing capacity and rigidity of the existing codes, such as ACI(1999), AISC-LRFD(1999), AIJ(1997), BS5400(1979) and DBJ13-51-2003(2003) is compared.更多还原
