摘要
为了减少大跨度梁高取值设计的计算工作量，使一次设计的梁高就能满足要求，通过对决定梁高的4个因素：满足挠度要求、最大配筋率、最小配筋率和梁断面的经济取值分析，推导出确定大跨度梁高的最小取值计算公式，其结论在已完成的实际工程设计中得到了验证。
The calculation formula of the minimal height of large-span bearn is deduced in this paper from the four relevant factors,such as meeting the needs of deflection,the maximum and minimum ratio of reinforcement,reasonable cross section of the beam.The methodmentioned here has been proved to be helpful in an actual project design.It can be used to reduce the design calculation and improve theeconomic benefit in application and satisfy the requirement ouly after the first design procedure.
