查询词典 compressive stress

The results of lattice beam internal force calculated method based on double parameter groundsill model are more approach the experiment measured values because of consideration of the pass of shearing force in soil, and its calculated workloads are similar with the method of winkler elastic foundation. Besides, the thesis also discusses the moment of torque affected results on node stress situation and the correction of stress value at the bottom of cross node of lattice beam. Due to the repeat calculation of node area during internal force calculation, the stress value of the bottom of beam is lower, this may lead the calculated value unsafe, but the corrected stress value will more approach to practical situation.
