About


I am involved in teaching courses on Applied Mechanics and Dynamics. My research interest includes earthquake engineering with balanced emphasis on structural and geotechnical engineering. Some important milestones of my research group may be enumerated as follows:

(a) Using principles of applied mechanics and through advanced numerical studies, potential danger of amplification in response due to two-component shaking relative to one-component counterpart has been uncovered. To obviate the tedium of bi-directional analysis, a novel strategy which requires less-rigorous uni-directional analysis has been evolved. This eliminates the need of estimating structural response for all admissible incidence angles, too. This development has been shown generalized irrespective of site characteristics. This can succesfully help estimating seismic damage under bi-directional shaking.

(b) A generalized and robust approach to construct seismic fragilities has been introduced using spectrum matching. This method works well for any geotechnical and structural systems both under real and synthetic records. 

(c) Potential danger of  landsides during earthquake  has been comprehensively investigated leading  to a simple formulation  of  the  intensity of shaking  correspodning to the incipient landslide. By means of introducing formal dimensional analysis, a simple method to estimate the order of permanent displacement has been proposed.

(d) Several contributions  on the implications of soil-structure interaction  covering  wide range of civil engineering  structures have led to the meaningful solutions of many challenging problems of practical interest. By astute application of the principles of mechanics, methodology towards estimating lateral capacity of piles has been developed.

(e) Challenges  associated  with  irregular structures  has been elaborately explored with  due  cognizance  to  soil-structure  interaction  taking into  account  the  emerging concepts  and challenges relevant to  (a) interdependency between strength and stiffness, (b) multistory systems in contrast  to  single  story companion  and  (c)  inherent  uncertainties  in ground motions. Concatenation of these studies evolves the important guidelines of  mitigating  dangers  of  structural  irregularity.
