Reliability Analysis of Continuous Beam Using Hasofer-Lind Reliability Method

This project work “Reliability analysis of a continuous beam using Hasofer-Lind Reliability Method” was primarily concerned with the effect of varying parameters such as load, modulus of elasticity, moment of inertia and span length on the reliability of a continuous beam. The limit state considered is deflection, and the allowable deflection is specified as L/360. The maximum deflection is 0.0069wL^4/EI and it occurs at 0.446L from either end (AISC, 1986). Reliability analysis, expre...

Analysis of Short Cylindrical Shell Under Internal Liquid Pressure Using Improved Finite Difference Method

ABSTRACT This research work presents the static analysis of short cylindrical shell under internal liquid pressure with various boundary conditions and aspect ratios. Improved fourth order finite difference method was employed for the analysis and a MATLAB computer program was developed based on the matrix equations and models generated from the analysis. The following boundary conditions were covered in this research; short circular cylindrical shell simply supported at both edges(s-s), sho...

Application of a Direct Variational Principle in Elastic Stability Analysis of Thin Rectangular Flat Plates

ABSTRACT The purpose of this work is to use the energy approach in the form of direct variational principle (Rayleigh-Ritz method) for buckling analysis of thin rectangular plates with various boundary conditions using Taylor series shape functions. To do this, thin rectangular flat plate of various boundary conditions with three dimensions Ly, Lx and t was analyzed in this research. Ly and Lx are secondary and primary in-plane dimensions respectively and t is the plate thickness. The bou...
