摘要
根据大型多纵梁矩形渡槽槽身结构及其受力特点,提出了实用空间分析法,使复杂的空间结构计算分离成相互联系的两个平面问题。横向计算中,底部弹性支承在各纵梁上,可求得结构的横向受力与弹性支承反力;然后将弹性反力作为荷载,反向作用于侧墙和中间纵梁上,进行纵向梁的受力计算。算例分析表明,该计算方法合理、快捷,能够满足设计要求。
The practicality space analysis method is suggested according to structure endure force character of large rectangle aqueduct with multi-longitudinal beams, thus making the complicated space structure calculation decompose into two related plane problems. In cross calculation, the structure subject to cross force and the reverse force of elasticity support can be derived from the bottom elasticity support on each longitudinal beam; then, with the elasticity reverse force as the loading reversed acting on the side walls and the middle longitudinal beam, the longitudinal beam subject to force can be calculated. The analysis of calculated examples indicates that this method is rational, agille and able to satisfy the design requirements.
