Abstract: Historically, truck regulations have maintained controls on axle and gross weights with legal load formulas based on limiting allowable stresses in certain types of bridges. These stress limitations do not usually lead to ...

Abstract: Crack propagation in a rotating inner raceway of a high-speed roller bearing is analyzed using the boundary integral method. The model consists of an edge plate under plane strain condition ...

Abstract: The current AASHTO design loads were developed more than 40 yrs ago based on truck traffic in operation in that period. The code, however, has produced safe designs despite the vastly increased legal loads and reduced ...

Abstract: Recent studies have successfully introduced genetic algorithms (GA) to identify the important failure modes of complex structures and quantify their contributions to the reduction of the reliability of structural systems. ...

Abstract: Stiffened Z-section beam purlins were tested to evaluate the deflection behavior of lap joints under combined bending and shear. The tested beams had a span length of 243.84 cm (8 ft), nominal web depths of 20.32 cm (8 ...

Abstract: This paper develops a new solver to enhance the computational efficiency of finite-element programs for the nonlinear analysis and reanalysis of structural systems. The proposed solver does not require the reassembly of ...

Abstract: Recently observed increases in the numbers of permitted and illegal overweight trucks travelling over U.S. highways have raised concerns over their contributions to the reduction in the service lives of pavements and bridges ...

Abstract: Historically, truck weight regulations have maintained controls on axle and gross weights with legal load formulas based on limiting allowable stresses in certain types of bridges. These stress limitations do not usually ...
