摘要
本文依据平板网架拟板法 ,对三向类正六边形网架进行弹塑性变分求解。由最小势能原理解出网架弹塑性变形的挠度 ,进而推求网架上、下弦杆件的内力和截面。
This paper provided elastic plastic solutions of hexagon three way type space grids with variation principle which based on the plate analogy method of space grids. The elastic plastic deflection was obtained by means of minimum potential energy, and the internal forces and sections of upper and lower chords of the space grids was achieved. The solution can be used in elastic plastic analysis of other truss type space grids.
