Shear strength of connections between concrete filled steel tubes and beams Li Jian Architecture and Civil Engineering School Inner Mongolia University of Science and Technology, Baotou, China nkdlj@163.com Keywords: steel tubular column; joint; shear strength Abstract.
Therefore, the framework of the vertical shear is not conducive to the shear capacity of the node. 3 Shear capacity of concrete filled steel tubular beam-column joints In practical engineering, used steel pipe concrete nodes form of circular steel tubular nodes and rectangular CFT node.
Comparison of the calculated values ​​with the experimental values 4 Conclusions 1) During the steel tubular column and beam joint design, in addition to follow: “weak beam principles” of, also deal with the shear strength of the node checking. 2) Shear strength formula (10) are in good agreement with the experimental results for engineering design.

Experimental research on tensile strength of premixed concrete at early ages Li xiaofen1,a, Ren Ping2,b 1School of Architectural Engineering, Zhongyuan University of Technology, Zhengzhou 450007,China 2School of civil Engineering, Henan University of Urban Construction, Pingdingsan 467036,China aLi_xiaofen2010@163.com，b14851338@qq.com, Keywords: premixed concrete; cubic compressive strength; direct tensile strength; splitting strength; early ages Abstract.
Introduction Tensile strength is one of the important mechanical properties of concrete, most of the time people use the method of splitting for the tensile strength of concrete In the reinforced concrete engineering, because axial tensile test is difficult, contrast, splitting tensile test is simple.
So splitting tensile strength can be estimated in the same period by early concrete cube compressive strength measured in formula (3) to guide the construction and production in engineering. 2.4 Relationship between the axial tensile strength and the cube compressive strength After adding the factor of age in code [4], the formula about the relationship between axial tensile strength and compressive strength becomes : 　　　　 　　 　 　 （4） With the ratio of value calculated of the axial tensile strength by the formula (4) and test value in this paper, n is equal to 15, μ is equal to 0.9268，σ is equal to 0.061，δ is equal to 0.066，the four indicators show that formula is better consistent with test results in this paper, at the same time, it can also satisfy the requirements of engineering applications.
