Introducing Niraj Malla, a dedicated researcher with a solid academic foundation, holding Master’s and Ph.D. degrees from the Tokyo Institute of Technology. Niraj’s expertise lies in the specialized fields of earthquake engineering, performance-based seismic design of buildings and bridges, and soil-structure interaction. Currently, he is working as a bridge engineering for Katahira & Engineers International, Japan.
Experience
April 2022 ~ Present: Structural engineer at Katahira & Engineers International
Major Responsibilities:
Design of sructural components of the bridges.
Modeling and analysis of the bridges in MIDAS CIVIL considering permanent and transient loads.
Analyzing the bridge considering the soil-pile-structure interaction of the bridge.
Assuring the ductility capacity of the bridges using pushover analysis.
Developing the VBA codes in the spreadsheet for facilitating the design.
