The design of structures for strength.
thesisposted on 2023-05-26, 20:06 authored by Lam, P
The philosophy of design of structures by picturing statically admissible states is outlined and applied to various members and structures. The strength of bolted joints under eccentric loading is investigated. The concept of thrust line is applied to multi story bay frames and space frames, and a graphical method of minimum weight design by guessing points of inflexion is presented. Various solutions for the load-carrying capacity of orthotropic slabs are proposed. The strength and safety of the Gladesville Arch Bridge is investigated; the load factors for the bridge are established for three different loading conditions. An experimental method for directly obtaining a shape for an arch dam under a given loading condition is proposed. Load-carrying capacity of arch dams are also estimated by picturing various statically admissible states. The relation between deflexion, buckling, and strength is discussed. The concept of Non-Euler Buckling is introduced. Various practical design considerations are summarized, including the detailed design of joints. In the appendices, tests on arches, slabs, and a shell are reported, together with related calculations. The numerical method of Dynamic Relaxation is applied to the problem of estimating deflexion in elasticplastic frames, the elastic stability problem of over-braced frames, and the non-linear analysis of structures made of,materials having no. tensile strength.
