空腹钢梁作为一种特殊构件，其内力特征比较复杂。空腹钢梁的弦杆和竖腹杆均承受有弯矩、剪力和轴力。本文总结空腹钢梁内力计算公式，提出了空腹钢梁的加强措施，并通过有限元计算，对其进行了验证和比较。
空腹鋼樑作為一種特殊構件，其內力特徵比較複雜。空腹鋼樑的絃桿和豎腹桿均承受有彎矩、剪力和軸力。本文總結空腹鋼樑內力計算公式，提齣瞭空腹鋼樑的加彊措施，併通過有限元計算，對其進行瞭驗證和比較。

Hol ow steel beam as a special component that has the complicated characteristics of internal force. Both of chord member and vertical web member bear moment, shear force and axial force. This article summarizes the internal force calculation formula of hol ow steel beam, and puts forward the strengthening measures and compare and testify by finite element analysis and calculation.
