ANALYSIS OF BEHAVIOUR IN THE SINGLE-STOREY BUILDING FRAME STRUCTURE WITH CRACKS SUBJECTED TO RANDOM LOADS

Abstract

The paper presents the calculation and behavioral analysis of a single-storey building frame structure with cracks under random loads. The frame structure is assumed to have a crack with a determined depth and a given position. The problem of the paper is to analyze the oscillator of a system of one-degree freedom subject to white noise excitation by using analytical method and Monte Carlo simulation. The results obtained in this paper are the second order moments of horizontal displacements and velocities of the one-storey frame structure. In order to feel the behavior in the structure, this paper has conducted thorough considerations to clarify the effect of crack depth, crack position, viscous damping coefficient and white noise intensity to the quantities considered.
