本文对以18号热轧工字钢为轴心受压杆件的承载能力进行了试验和理论研究。
This paper presents the experimental investigation and theoretical analysis for the ultimate load-carrying capacity of axially loaded compression member of No. 18 rolled I-section.
基于能量法原理建立了受压节点承载能力的理论表达式，得到了其极限载荷的上限理论解。
The bearing capacity formulas of the joints under compression were also found out by the energy method and experimental method.
打入桩，桩径较小，水平承载能力很低，人们一般只用它承担垂直荷载，这样可近似按轴向受压构件计算。
Having shorter diameter and lower lateral bearing capacity, driven piles are usually used to carry vertical load and can be calculated as axial compressed member.
