A Practical Response Spectrum Method in Considering the Input Angle of Seismic Excitation Shimei Liu a and Lingtao Xia b Department of Architecture and Civil Engineering, Zhejiang College of Construction, Hangzhou 311231, China ashimeiliu126@126.com, bxialingtao@163.com Key words: input angle; plane; displacement response spectrum; a practical response spectrum.
In the engineering seismic analysis, generally assumed ground motion input direction is parallel to the horizontal and vertical axes of the structure, for in-depth analysis of ground motion input direction on the structural response, it is assumed that the input direction parallel to the X axis and Y axis respectively.

Nonlinear Stability Analysis of Qijiadu Long-Span Deck-Type CFST Arch Bridge Liang Xu 1,2, a, Yaping Wu 1,b 1 Lanzhou Jiaotong University, China 2Northwest University for Nationalities, China axl1927@163.com, bwypsw@163.com Keywords: Concrete-Filled-Steel-Tube; Arch Bridge; Transverse Stability; Geometrical and Material Nonlinearity; Plate-Type Rubber Bearing Abstract With the application of the composition material-concrete-filled-steel-tube (CFST) in civil engineering, the crossing ability of arch bridge gets advanced development.
Although the theory of bifurcation buckling is based on the condition that idealistic straight bar under compressive load, the method can be applied to the engineering structure analysis directly.
Engineering Summary The Qijiadu Yellow River Bridge is located upriver from the dam of Liujiaxia Reservoir, and its distance from dam is 4.2 kilometers.
The obtained safety coefficient is less than 4~5, a number that used by engineer in design.

Experimental and Theoretical Studies on Compressive Stress-strain Relationship of Phosphogypsum-lime-flyash-gravel Mixture WANG Wei1, a , WU Shilong2,b and YANG Dexi 2,c 1 Department of Civil Engineering, Shaoxing University, Shaoxing 312000, China 2 Research Institute of Geotechnical Engineering, Hohai University, Nanjing 210098, China a wellsking.wang@gmail.com, b geowjh@tom.com, cgeosx@tom.com Keywords: phosphogypsum mixture; laboratory test; strain-stress curve; mathematical model; strain softening Abstract.
It should be noted that this is different from softening property of grave and hardening property of PG and fly ash [11], which deserves enough attention for engineers during engineering design.
Unfortunately, they can not express softening type SSC of PLFG, which often reduce simulating accuracy of engineering design and lead engineering accident.
(1) Triaxial compressive SSC of PLFG appears hardening behavior with big confining pressure, but it appears obvious softening behavior with small confining pressure, which deserves enough attention for engineers during engineering design

Testing and analysis of bearing capacity on pile foundation Yanpeng Zhu1,a Zexue Bao1,b Tianzhong Ma1,c Chunjing Lai1,d 1School of Civil Engineering, Lanzhou University of Technology, Lanzhou730050, China azhuyp@lut.cn, b906167749@qq.com, c4441140@qq.com, d350146922@qq.com, Key words: Pile foundation testing; Static load test; Anchor pile; Abstract.
However, the static load test and low strain test play a very important role in pile foundation inspection and ensurement of the quality of pile foundation engineering.
However, pile foundation engineering belongs to hidden engineering, its quality is directly related to the safety of structures, and once pile foundation has any accidents, reinforcement treatment is also difficult and high-cost.
The piles of 6600 kN used different four engineering piles as the anchor, the piles of 4000kN adopted some additional new anchor piles.
