With Different Axial Compression, the Finite Element Analysis of Concrete Frame Column that Reinforced by Assemble Inclined Web Steel Truss Zhang Shaowu1,a, Chen Yingchuan2,b, Zhang Gengbiao3,c 1School of Civil Engineering, Shenyang Jianzhu University, Shenyang, China 2School of Civil Engineering, Shenyang Jianzhu University, Shenyang, China 3School of Civil Engineering, Shenyang Jianzhu University, Shenyang, China a578461228@qq.com, b896468068@qq.com, c569680497@qq.com Key words: Different axial compression, Inclined web steel truss, Reinforcement performance, ABAQUS, Bearing capacity, Ductility Abstract.
Introduction Encased steel reinforcement method has been widely applied to practical engineering reinforcement because that construction is simple, convenient and less impact on the member section, but it can significantly improve the vertical and horizontal bearing capacity of components and increase the cross-sectional stiffness.
However, the current engineering and research in this field show that outsourcing steel reinforcement columns is more than beams.
ABAQUS as a powerful engineering simulation finite element software, users only need to provide some data, it can analyze the most complex structures (stress / displacement) problems, and even highly nonlinear problems.
Because of excellent analytical ability and reliability, ABAQUS is widely used in engineering research and plays an important role.

Damage localization for a continuous beam by the displacement variation Zhu Jiawei1, a, Zhou Danting1,b ,Yang Qiuwei1,c 1Department of Civil Engineering, Shaoxing University, Shaoxing, 312000, China a772107058@qq.com, b395651718@qq.com, cyangqiuwei79@gmail.com Keywords: damage localization; continuous beam; static test data; displacement variation.
Since the static equilibrium equation is solely related to the structural stiffness, and accurate static response data can be obtained rapidly and cheaply, the static-based methods have attracted relatively more attention in the civil engineering field.

Influence of Bagasse Ash as Partial Replacement of Cement on Soft Soil Improvement Hatairat Poorahong1,a, Naphol Yoobanpot2,b* 1Graduate student, Department of Civil Engineering, Faculty of Engineering, King Mongkut’s University of Technology North Bangkok, Bangkok, Thailand. 2Department of Civil Engineering, Faculty of Engineering, King Mongkut’s University of Technology North Bangkok, Bangkok, Thailand.
Introduction Soil improvement is one technique widely used to reduce the problem of geotechnical engineering project which construct on such soft clay.
It is well know that soft clay have the poor engineering properties are low shear strength, low bearing capacity and high settlement [1].
The application of BA in civil engineering work has been proposed by some researchers.
