A new formula is produced to calculate dynamic stress intensity factors of simply supported beam containing a single edge crack in this study. Firstly, the weight function for simply supported beam containing a single edge crack was derived from a general weight function form and two reference ...
6) Simply Supported Beam of Variable Cross-section 变截面简支梁 1. In connection with machining of the stepped shaft,establishes a mechanics model of bending deflection,deduces a universal formula-an equation of deflective skew curve-for simply supported beam of variable cross-section bending ...
Simple formulae for the initial collapse loads of clamped and simply supported beams along with analytical expressions for the finite deflection behaviour of clamped beams are presented. The simply supported beams display a softening post-yield response, while the clamped beams exhibit hardening ...
In this work, a control strategy based on fuzzy sliding mode control (FSMC) is applied to effectively manage the large-amplitude chaotic vibrations exhibited by a simply supported beam. The analysis considers the nonlinear beam structure, which is subjec
A horizontal simply supported beam(illustrated below)with a square cross-section(10cm×10cm) is subjected to a combination of a point load and a distributed load as shown below. The beam is made out of steel with a Young's modulus of190GPa,...

Using the diagram multiplication method, we introduce an analytical formula for a novel damage-identification indicator, namely the diff erence of rotational-angle influence linescurvature(DRAIL-C). If the initial stiff ness of the simply supported beam is known, the analytical formula can be ...
Test results for the shear behavior of 13 monolithic and 14 segmental(epoxy jointed and dry jointed) simply-supported externally prestressed concrete model beams are employed for formulating a simplified method of calculating the shear bearing capacity.Based on the test results,a regression formula for...
[18], using a simply supported composite beam bridge as the engineering background, investigated the actual load-bearing capacity of the reinforced bridge based on field load testing methods. Li et al. [19] conducted load testing analysis on the Xitang Bridge, indicating that the concrete-filled...
Each multi-column bent consists of a reinforced concrete bent beam that measures 1066.8 mm in width and 1219.2 mm in depth. This bent beam is supported by three circular reinforced concrete columns, each with a diameter of 914 mm and a height of 4600 mm. In terms of reinforcement, the ...
