In this article, we propose a powerful method called
homotopy perturbation method (HPM) for obtaining the
analytical solutions for an non-linear system of partial
differential equations. We begin this article by apply HPM
method for an important models of linear and non-linear
partial differential equations.
Calculation of fire resistance for any structural member divided in two independent steps . The first step involves predicting the temperature distribution inside the structural members, referred to as ‘thermal analysis’. The second step of the analy
sis, termed the ‘structural analysis’, is carried out for the main purpose of determining the response of the structure due to static and thermal loading. The first stages of analysis are discussed in this paper, using finite element method by a structural analysis program " ANSYS "
