摘要
本文根据均布载的假设,从能量原理出发,建立虚功方程,讨论四边简支井字梁的弯矩计标,推出简化计算公式,计算简单实用,且精度较高。
This paper discussed the simply supported on four sides reinforced concrete coffering beam struc-
ture, according to the supposition of uniform load, and basld on the energy prmciple, virtual work
equation is established,The formulas for calculating the moment are proposed in the paper,this method
is quite convenient,acurate and practical.
