本文介绍一种通过在等截面大跨度梁的两端各延伸一定长度的悬臂梁来减少梁的跨中挠度而相应地降低其截面高度的方法。确定出悬臂梁的臂长与大跨度梁的跨度比值,通过这个比值,可在工程设计中很方便地选择相应于不同跨度的悬臂梁长度。同时给出了工程设计中常用的三种跨度较大的梁的悬臂长度与其跨长的比值表格供查用。

A method reducing the section depth and middle bay deflection of wide spanning through proper extencrg its two pn is cntroduced.From the length ratio of suspended beams and wide spanning beams,the length of suspended beams to distinctive spanning is selected conveniently.At one time, the table alout ratio of bay and suspend length of three distinctive wider spanning beam that is often emerged in engineering design is presented for consulting
