The bridge across Chambal River consists of two approach bridges and a cable stayed bridge with concrete girder and pylon. And the main bridge has been designed mainly based on AASHTO LRFD. This article covers design specifications from AASHTO LRFD, which are applied to load combinations and structural verification. And it also covers local standards applied in definition of loads such as live load, wind load, temperature, etc. In addition, the difference between applied design specifications and Korean standards is mentioned in this article briefly.

This paper presents a comprehensive study of pressure developed on different faces of a 'Y' plan shape tall building using both numerical and experimental means. The experiment has been conducted in boundary layer wind tunnel located at Indian Institute of Technology Roorkee, India for flow condition corresponding to terrain category II of IS:875 (Part 3) - 1987, at a mean wind velocity of 10 m/s. Numerical study has been carried out under similar condition using computational fluid dynamics (CFD) package of ANSYS, namely ANSYS CFX. Two turbulence models, viz., $k-{\varepsilon}$ and Shear Stress Transport (SST) have been used. Good conformity among the numerical and experimental results have been observed with SST model yielding results of higher magnitude. Peculiar pressure distribution on certain faces has been observed due to interference effect. Furthermore, flow pattern around the model has also been studied to explain the phenomenon occurring around the model.
