摘要
楼面结构中,大多数板是不规整的连续板。现用的不规整连续板计算方法不能满足工程实践的需要。有的简化算法被滥用。举例论述了滥用简化算法会带来20%或更大的误差。沿长度方向各跨的跨度不相等会导致误差;沿宽度方向各跨的跨度不相等也会导致误差。并且,板的厚度不均匀也会导致误差。
Most of plates in building floor structures are irregular continous plates.However,the existing calculation methods for these plates can not meet the needs of the practical engineerings,and some simplified methods are used wrongfully.By some examples,it is discussed that to use wrongfully simplified method can cause a relative error such as 20 percent or much more.The nonuniformity of all spans along plate's length can cause an error,and the nonuniformity of all spans along its width can cause an error too.In addition,the nonuniformity of plate's thickness can cause an error.
