Abstract

In accordance the standard bridges, seismic loads must be taken into account in the combinationof loading conditions. Often the continous bridge model is a choise, especially on the model ofbridges with spans of more than 1 (one). This analysis focused on the piers of a bridge that consitsof 5 (five) spans. The variable in this model is layout of continous or simple beam. In this analysismade 5 (five) types of the bridge. To obtain the optimal and accurate design, use a dynamicanalysis by response spectrum based on the PGA value in SNI 03-1726-2002. With the pushovermethod using SAP 2000 software will be acquired and the value of Demand and CapacityDisplacement, so can to know the feasibility on the piers of a bridge modeled. Results of analysisthat only model IV incapable supporting the magnitude of longitudinal displacement. As for thetransverse direction of all the models capable to hold the magnitude of transverse displacement.Ductility of pier P1 and P2 for all models meet the requirements of the maximum ductility μD ≤ 5for multiple piers. Overall, the optmum behavior performance to resist earthquake loads is themodel II.

Abstract

The finite element method is a method of modelling of an object to divide into smaller parts as awhole still has the same properties as the whole thing before it was divides into smaller sections(discretization). The finite element method can be used to analyse various types of structures, suchas plane truss, space truss, plane frame, space frame, beam, and grid.The main difference space truss and space truss are the number of degrees of freedom at eachnode. Each bar in order to space has six degrees of freedom. A space truss structure formed by thecombination of elements order in XYZ space. Variations of incorporation requires thetransformation of the characteristic elements of the local coordinate system to the globalcoordinate system.In this study, analysis of space truss using the finite element method will be assisted with thesoftware Matlab. Where the result of Matlab will be compared with result from the SAP2000. Theresults of this analysis are joint displacement, joint reaction, and element forces.Keywords : Finite Element Method, Space Truss, Matlab
