摘要
为提出一种简单可行的框架深肋组合扁梁的抗弯承载力计算方法,通过试验研究塑性受力阶段深肋组合扁梁的截面应力状况,提出框架深肋组合扁梁的承载力极限状态的破坏机制;推导出简化的深肋组合扁梁负弯距区的抗弯承载力公式,并利用已研究的正弯距区抗弯承载力公式,得到框架抗弯承载力的计算公式.计算公式的合理性和正确性得到了试验的验证.
To present a simple and feasible method to calculate the bending resistance of frame composite slim beam with deep deck, the stress distribution of sections in plastic stage was studied by tests, and the failure mechanism of the ultimate resistance was proposed. The formula of calculating the bending capacity in the hogging moment region of the slim beam with deep deck was deduced. Along with the existing formula of sagging moment, the calculation formua of the frame slim beam was obtained. Test results verify the feasibility of the obtained formula.
