Analisis Perhitungan Gaya Internal Rangka Ruang dengan Menggunakan Metode Elemen Hingga

Abstract

The finite element method is a method of modelling of an object to divide into smaller parts as a
whole 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, such
as 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 each
node. Each bar in order to space has six degrees of freedom. A space truss structure formed by the
combination of elements order in XYZ space. Variations of incorporation requires the
transformation of the characteristic elements of the local coordinate system to the global
coordinate system.
In this study, analysis of space truss using the finite element method will be assisted with the
software Matlab. Where the result of Matlab will be compared with result from the SAP2000. The
results of this analysis are joint displacement, joint reaction, and element forces.
