Analysis Of Gradually Built Structural System
Journal Title: IOSR Journal of Mechanical and Civil Engineering (IOSR-JMCE) - Year 2018, Vol 15, Issue 1
Abstract
The paper deals withthe analysis of structural system that built gradually such that the structural stiffness varies with time of construction. The analysis of such structural system is carried out by applying finite element method. First, all of the finite elements are included in the computation of number of degrees of freedom. Then, the analysis is initiated by considering all of elements and the numbering of degrees of freedom are carried out. Assembled elements are denoted by assigning the value of modulus elasticity, and absent elements are denoted by assigning zero modulus of elasticity. Nodal degrees of freedom that are located in absent elements are suppressed from the global equilibrium equation. Hence, the analysis is performed with changing global structural stiffness. A computer package program in FORTRAN is written for the analysis. The new package program is applied in the analysis of several study cases.
