This study performed the three-dimensional nonlinear finite element analyses using a general purpose finite element program ABAQUS to simulate the structural behaviors of two full-scale H-beam to box-column subassemblage specimens in fire test. In the experimental program of this study, the two specimens were tested at elevated temperatures in the furnace and under the specified constant loadings, and the moment connections of the two specimens were made of fire-resistant steel and normal steel respectively for comparison.

In this paper, material properties of the segment of the porous metal-bonded diamond grinding wheel were researched by finite element simulation. Segments were manufactured according to the design result and their elastic modulus was measured. The key points are as follows: The influence of the porosity on the elastic modulus was analyzed through a finite element method. In the FEM model, the design variable only includes the porosity, and the tetrakaidecahedron model is applied as the microstructure model of porous metal matrix. The corresponding porosity was decided in order to meet the requirement of the elastic modulus.

It is an error for an element from the XSLT namespace to have attributes with expanded-names that have null namespace URIs (i.e. attributes with unprefixed names) other than attributes defined for the element in this document.

假如一个XSLT元素拥用一个扩展属性（该属性不是本文档中为该元素定义的），而该属性的名字却不拥有一个非空的命名空间URI（例如：属性的名字没有任何前缀）（拥用空的命名空间URI），这将被认为是一种错误。

The conception of the edge element was firstly proposed by Whitney in 1957. At the beginning of 1980\'s, Bossavit and Verite put it to practical application to three-dimensional eddy-current problems. In 1987, Barton and Cendes applied the tetrahedral element to three-dimensional magnetic calculation.
