Analysis of Large Deflections in Structures

摘要

The purpose of the investigation is to develop equations which predict the large nonlinear deflections of a diamond-shaped frame subjected to loading in tension or compression. Two frames with different combinations of pinned and fixed joints are analyzed through large deflection nonlinear, small deflection nonlinear, and linear (analytical and matrix) analyses so that a comparison of the theories might be made. The results of the large deflection nonlinear analysis are found to agree very well with actual experimental data. A linear matrix analysis of a multi-bay Vierendeel truss is also developed and compared with experimental data. (Author)
