| 摘 要： | 本文研究了跨中出次梁相互连接的平行主梁体系的屈曲问题,以次梁对主梁提供侧向和扭转约束。得到了问题的解析解,给出了使主梁计算长度减半的次梁临界刚度,对刚度小于临界值的情况亦给出了屈曲弯矩和次梁约束刚度间的关系。

| Abstract: | The elastic buckling of parallel girders joined by secondary beams at the midspans wasstudied in the paper. An analytical solution has been obtained by considering that thesecondary beams prvided both lateral and torsional restraints to the girders. The criticalstiffnesses of the secondary beams which can reduce the effective length of the girders byhalf were given. The relationship between the buckling monents and the restraint stiffnessof the secondary beam was also given when the stiffness was less than criticak value. |
