In order to validate the grillage method met the requirements of engineering precision in calculation about box girder bridges, the grillage model and the plate element model of the bridge were built by using the finite element software Midas/Civil; under the premise of the same loading location and the load value, the deflection values and the stress values calculated from the two models were compared, and the corresponding error ranges were obtained.
The results show that the differences between them meet the engineering accuracy and using the grillage method in box girder bridges is reasonable.
The model of the box girder bridge was built by using the grillage method in engineering.
The plate element model was used by quadrilateral plate element when Midas/civil was used to build models.

Introduction Civil air defense engineering is an important infra-structures in city construction, it can ensure the safety of the people living in the city.
However, civil air defense engineering is exposed to various external loads such as earthquakes, humidity, especially explosive loads.
However, when damage occurs in civil air defense engineering, the difference of frequency is very small, and the frequency changes sensitive to temperature, humidity, while the mode shape varies less sensitively.
This paper adopts ANSYS 10.0 software to disperse soil and civil air defense engineering structure.

Buckling of Composite Thin-Walled Members Seungsik Lee1,a, Soon-Jong Yoon1,b , and Sung-Yong Back2,c 1 Department of Civil Engineering, Hongik University, 72-1 Sangsu-dong, Mapo-gu, Seoul 121-791, Republic of Korea 2 Department of Civil Engineering, Inje University, 607 Obang-dong, Gimhae-si Gyeongnam 621-749, Republic of Korea a drslee@naver.com, bsjyoon@hongik.ac.kr, ccivsyb@inje.ac.kr Keywords: buckling, pultruded members, experiment, beam theory, FE analysis Abstract.
The use of pultruded fiber reinforced polymeric (FRP) members in civil engineering applications can greatly reduce construction time and maintenance cost of structures, because pultruded members have high specific strength and excellent corrosion resistance compared to steel and concrete.
Pultruded members for civil engineering application are mostly made of a polymeric resin system reinforced with E-glass fibers and, as a result, they have low elastic moduli.
Introduction Fiber reinforced polymeric (FRP) members used in civil engineering applications are usually manufactured by pultrusion technique.
Unlike other composite materials for aerospace and mechanical applications, FRP members for civil engineering applications are generally reinforced with E-glass fibers of which cost is lower than that of others such as carbon, aramid, boron fibers, and so on.
