摘要
本文提出斜放四角锥平板网架内力计算的修正假想弯矩法。与假想弯矩法相比,该法考虑了四角锥单元上弦节点扭转剪力的影响,更合理地反映了斜放四角锥网架的受力特点,是一种计算精度较高的简化计算法。
The modified imaginery moment method for Computing the internal forces of inverted pyramid plane type space truss with diagonalon is proposed In it account is taken of the effect of torsional shear at the point of uppen chord of a pyramid element compared with the imaginary moment method, and the character of the truss under load is represented reasonably. Therefor this modified method is a simplifed method with higher accurate.
