Future fast track model for new road over bridge spanning over railway yard- ...Rajesh Prasad
Implementation of 4 lane cable stayed road over bridge is nearing completion. It is felt that it could be a future fast track model for construction of ROB over busy railway yard in India
Sustainable Solution for Shoring Method of Cross-Creek Bridge in Ankeng MRT S...Dr. Amarjeet Singh
In the Ankeng Light Rail MRT system (ALRMS) project, the U7 box girder passes crossing the Erbads creek and needs a temporary supporting system for the construction work. In this study, three temporary shoring system options were proposed to be the construction method. The D-B Contractor, New Asia construction and Development Corporation, evaluated and selected the optimal choice, The Steel truss frame with supporting beams, to serve as the temporary supporting system. Compare the deflection of Δmax and Δactual, which are 1.609 cm and 1.59 cm, respectively. This result presented that the shoring system composed of the H912*302*18*37 supporting beams and steel truss frame had achieved outstanding performance and work to construct the U7 box girder. This paper presents how the three options are evaluated and the detailed construction processes along with the survey verification for the method.

Handbook cum coffee table book titled staying with cables a modern construct...Rajesh Prasad
In India constructions of cable stayed bridge are far less than the construction of such bridges in advanced countries. The concept and technical know how in India is relatively new but after execution over busy yard Barddhaman- a very busy station and yard, the construction of cable stayed bridges is going to play important role in time to come specially at stations where there is a need to use the yard and land mass for future yard remodeling and passenger amenities.This hand book cum coffee table book has been made by Rajesh Prasad to share his construction experience for education purpose.

Design & Analysis of High rise Building With & Without Floating Column Using ...IJSRD
At present buildings with floating column is a typical feature in the modern multistory construction in urban India. There are many projects in which floating columns are adopted, especially above the ground floor, where transfer girders are employed, so that more open space is available in the ground floor. As the load path in the floating columns is not continuous, they are more vulnerable to the seismic activity. Sometimes, to meet the requirements these type of aspects cannot be avoided though these are not found to be of safe. Hence, an attempt is taken to study the behavior of a G+15 multi storey building in which some storey’s are considered for commercial purpose and remaining storey’s are for residential purpose. This paper studies the comparison & seismic analysis of the multistory buildings with floating column and without floating column. Finally, analysis & results in the high rise building such as storey drifts, storey displacement, and Base shear were shown in this study. Design and Analysis was carried out by using Extended Three Dimensional Analysis of Building Systems (ETABS) Software.

Structural Design and Rehabilitation of Reinforced Concrete StructureIJERA Editor
Effective rehabilitation scheme for failed structure demands methodical analysis of various
causes of failure and intended service loads and other functional details, The actual study under deliberation is
the best example of rehabilitation Structural element – Basement RCC raft, failed to sustain uplift due to ground
water table. This paper dealt with the rehabilitation of basement RCC raft foundation considering various design
aspects like uplift due to ground water table, sub-soil properties and restriction on depth of raft to suffice
