Abstract: Current AASHTO and AISC specifications require that an intermediate transverse stiffener attached on the shear web panel be designed not only to have a proper bending rigidity to meet the simply supported condition when ...

Abstract: The equation for the required area of the intermediate transverse stiffener stipulated in the current AASHTO and AISC specifications was derived under the assumption that the transverse stiffener is subjected to an axial ...

Abstract: In box girders with wide flanges, an uneven flange stress distribution (the flexural normal stress is greater at the edges than that at the center of the flange), so-called shear lag (or positive shear lag), may occur ...

Abstract: In this paper, a displacement equivalence-based damage model for brittle materials is proposed. A new damage deactivation criterion, which depends on both the stress and strain states of the materials, is adopted. Based ...

Abstract: This paper focuses on the application of the damage model for brittle materials proposed in the preceding paper on theory. The evolution rule of damage derived using the Onsager relations is specified according to the ...

Abstract: Although siting of thermal energy storage systems in the vadose zone may be beneficial due to the low thermal conductivity of unsaturated soils, water phase change and vapor diffusion in soils surrounding geothermal heat ...
