lever space

The shell is divided into orthogonal or oblique crossing girder systems, which make up a space rigid frame structure, then an analysis is made of the endogen force of the shell structure based on the curved lever space rigid frame structure.

该方法通过将壳体结构离散成相互垂直或斜交的曲杆梁系组成的空间刚架结构，进而分析曲杆空间刚架结构的内力，达到壳体内力分析的目的。

The Method of Curved Lever Space Rigid Frame of Reinforced Concrete Shell Structure Internal Force Calculation Program Design

钢筋混凝土壳体结构内力计算的曲杆空间刚架法程序设计

The method of curved lever space rigid frame, a new and practicable numerical method, is based on the utility of reinforced concrete shell structure in practical project and on endogen force analysis of shell structure as this paper extracts.

从钢筋混凝土壳体结构的实际应用出发，对壳体结构内力分析提出了一种新型实用的数值分析方法&曲杆空间刚架法。
