چکیده
Abstract In order to study the stability performance of three-limbed steel tube latticed column, finite element numerical analysis method based on structural theory is adopted. Firstly, linear column without diagonal lacing bar carried out, and calculation elastic buckling load considering influence shear deformation obtained. Then, elastoplastic with are out. The studied when only global initial geometric defects, member both kinds defects considered at same time. results show that direct can be used calculate bar, error 6.67%. mainly depends defect negligible. And two applied time, reduced by less than 0.20% compared defects. analysis, determined defect. When decreases 0.65% only, 7.60% only. It concluded there little difference in overall bearing capacity between

Installing stone columns in the ground is an effective improvement technique to increase the load bearing capacity and reduce the consolidation settlement of the loose or weak cohesive soils. In addition to the increase in the bearing capacity and reduction in the settlement, stone columns can accelerate the dissipation rate of the excess pore water pressure generated by the surcharge, which ex...
