Build of stiffness matrix and nodal load vector of taper element of section I include shear force and connection stiffness

Abstract

ABSTRACT:

This paper show how to build stiffness matrix and load vector by energy method for taper, I section elements includes the effects of shear and semi-rigid connection, use for structural analysis problem. Mathematical model of the section is exponential.  Thereby, programming the structural analysis program for taper elements and verify results stiffness matrix, load vector as well as assessing the effects of shear and semi-rigid connection to force and displacement of this element.

Keywords:Taper elements; stiffness matrix; semi-rigid connection
