Performance of Integral Bridge by Addition of Cross Girders
Abstract: The bridges without expansion joints are Integral Abutment bridges (IAB’s). In conventional bridges, the bearings are generally corroded due to water seepage through joints which are avoided in IAB’s. However there will be stresses developed due to thermal induced movements of the bridge which is to be taken into account. In this paper, finite element analysis is carried out using STAAD ProV8i on a typical model of IAB. Here various …

Influence of Constant Micro Strain Levels on the Strength Properties of the Asphalt Concrete mixture
Abstract: Asphalt concrete mixture is designed to resist the deformation and vehicular traffic loading throughout its service life. However, when the asphalt concrete pavement practices over loading within the service life period, it exhibits cracking and rutting. In the present investigation, an attempt has been taken to understand the strength performance of asphalt concrete when practicing variable levels of constant stresses. Asphalt concrete mixture was prepared at optimum asphalt cement requirement …

Failure Analyses of 16 mm Thick SA 516 GR 70 Auto Clave
Abstract: With the acceleration of global industrialization, there is a demand for high-or low-pressure storage of liquids or gases. Because of the complicated operating conditions that will inevitably encounter a possible hazard, pressure vessel design is a critical responsibility. Previous failure studies have revealed that the presence of local loads and discontinuities increases pressure vessel fracture. As a result, a detailed examination of pressure vessel steel from the standpoint of fracture …
