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

Abstract

This study aims to get the relationship (correlation) between the shear strength parameters obtained from unconsolidated undrained triaxial test and direct shear test. The test results were analyzed using multiple linear regression analysis between the results of unconsolidated undrained triaxial tests, the results of direct shear test, and physical properties of the soil mixture to obtain a simple equation to estimate the shear strength parameters based on the results of unconsolidated undrained triaxial test, results of direct shear test, and physical properties of the mixed soil. By using multiple linear regression analysis, correlation shear strength parameters (c and ϕ) between the results of triaxial, direct shear test, and physical properties of soil tests is obtained. The Cohesion value of triaxial test results are bigger 1.1 to 1.3 kg/cm2 than the value of cohesion direct shear test for wet conditions with an average difference of 1,26kg /cm2 and 0.7 – 0,9kg/cm2 for dry conditions with average differences 0,892kg/cm2. While the value of the angle of internal friction of direct shear test results for wet conditions are bigger 24o - 42o than the angle of internal friction of triaxial test with average differences 35,138o and for dry conditions is bigger 1,7-19,7o than the angle of internal friction of triaxial test with an average difference of 11,56o. Keywords: triaxial, direct shear, correlation, shear strength
