Inner Force Analysis of Two Typical Frames with Vertical Displacement Wei Zhou 1,2 1.School of Material Science and Engineering, 2.
School of Civil Engineering, Harbin Institute of Technology; Harbin, 150090, Email: Zhouwei-hit@163.com Key words: Vertical displacement; framework with transferring layer; mega-frame; inner force Abstract: Finite element method is often used to obtain exact solution in the course of internal force calculation of some complex frames which contain nodal vertical displacement such as frames with transferring layer and mega-frames with sub-structure.
An engineering example is introduced, which is intended to provide reference for the simple calculation for the above said complex frameworks. 0 Introduction Frameworks with transferring layer and mega-frames with sub-structure are widely applied in new engineering structure as well as additional construction and storey adding of existing building.
Therefore, it is of theory and practical engineering value to introduce a simple internal force analytical method for frameworks containing nodal vertical displacement, based on the basic principle of displacement method and moment redistribution method.

Evaluation of Slope Stability Based on Fuzzy Grey Element-Matter Model based on Properties of Mechanics Shiguo SUN1, a, Yanyan HE 1,b 1 Architecture and Civil Engineering Department, North China University of Technology, Beijing, China,100144 assg918@163.com, b19890825502hyy@sina.com Keywords: Gray matter-element; Association transformation; Relational degree; Stability Abstract.
Introduction Slope engineering is an open complex system, so most of the factors affecting the stability are diverse, variable, incomplete and incompatible.
Fuzzy theory can be a good solution to fuzzy uncertainty in slope engineering, while the core of matter-element analysis theory is used to solve the incompatibility.
Currently, the fuzzy matter-element analysis has been applied to the slope engineering, which effectively solved the ambiguity and incompatibility between various factors.
