1、0 第十一章结构的极限荷载一、判断题：1、静定结构只要产生一个塑性铰即发生塑性破坏，n 次超静定结构一定要产生n+1个塑性铰才产生塑性破坏。2、塑性铰与普通铰不同，它是一种单向铰，只能沿弯矩增大的方向发生相对转动。3、超静定结构的极限荷载不受温度变化、支座移动等因素影响。4、结构极限荷载是结构形成最容易产生的破坏机构时的荷载。5、极限荷载应满足机构、内力局限和平衡条件。6、塑性截面系数sW和弹性截面系数W的关系为WWs。二、计算题：7、设uM为常数。求图示梁的极限荷载uM及相应的破坏机构。lMAB8、设极限弯矩为uM，用静力法求图示梁的极限荷载。ABC2lMPu/3l/39、图示梁各截面极限弯
