采用俞茂宏教授提出的统一强度理论，考虑轻骨料混凝土高压应力状态下的强度特性，建立了基于统一强度理论的多轴强度准则。

In this paper , a multi-axial strength criterion for LWA concrete is presented based on the Unified Strength theory proposed by Yu , which considers the strength characteristics of LWA under high compression .

最后，采用俞茂宏统一强度理论，针对一个具体的结构例子，分析了孔隙液体的可压缩性对结构弹塑性分析的影响。

Elasto-plastic finite element analysis based on the proposed constitutive equation and the Yu unified strength is also performed to study the influence of compressibility of pore fluid on the elastic limit load and load deformation relation of an example structure .

本文采用俞茂宏统一屈服准则对固支圆板、矩形板进行了塑性极限荷载分析，得出了相应的统一解形式。

In this paper , adopting the Yu 's ( Twin Shear ) Unified Yield Criterion , we perform the limit load analysis of two problems : one is fixed circular plate and the other is rectangular plate under uniform out-of-plane loading .
