About me
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, and soil-structure interaction.
What can you expect on this site?
This site is intended to share knowledge related to structural design, analysis, and seismic issues. Additionally, content addressing challenges in soil-structure interaction and geotechnical aspects (albeit not extensively, as it falls outside my primary area of expertise) will be shared on this platform. Lastly, opinion pieces from diverse experts presently involved in various engineering firms will be featured here. You can access relevant content under the ‘Topics’ tab.
Displacement-based design of bridge piers.
The current codes, such as AASHTO LRFD, emphasize a force-based design approach for bridge design. Depending on the structural type and importance category, the response modification factor R is recommended to reduce the elastic design forces. The basic idea is that acceptable deformation limit states are achieved by designing for the reduced forces. On ..
Displacement estimation of sheet pile
The limit equilibrium approach is used to estimate the force demand in the sheet pile. In other words, we assume that the soil has undergone enough displacement to trigger active soil pressure on one side and passive pressure on the other side, and we estimate the forces accordingly. However, this approach cannot be used to estimate the displacem….
Site-specific analysis of ground motion
Site-specific response analysis is conducted to account for the local geological and geotechnical conditions that can significantly influence the ground motion experienced at a specific site. In some cases, local design codes require the designer to perform site-specific response analysis, particularly when the soil is very soft (for instance, ASCE 7-16 mandates th…..
