1. Introduction
Seismic risk assessment and loss estimation are very much essential to minimize the probabilities of seismic hazards. Risk and loss values are useful for budgetary planning, estimating need of manpower for disaster management, educating and making aware to general public and systemize the retrofit applications [3]. Thus loss estimation methodology is an essential tool for earthquake preparedness. This also helps to estimate the insurance premium of building stock for a particular event. Probabilistic financial risk assessment methodologies have been very popular and are being used since last few decades. Recent studies based on seismic design philosophies and financial risk assessment methodologies suggest that repairing of minor to moderately damaged structures contributes significantly in seismic financial risk. Therefore philosophies like Damage Avoidance Design (DAD) have been proposed by Mander and Cheng [14] for bridge substructures which showed better performance without causing any structural damage. The triple integration equation developed by Pacific Earthquake Engineering Research (PEER) Center for probabilistic seismic risk assessment is often used to approximate the probability of exceeding a performance requirement. Further Dhakal and Mander [5] have extended the PEER framework formula to a quadruple integral by including time, thereby enabling the quantification of seismic risk in terms of expected annual loss (EAL). This equation certainly is more useful which allows integration of all probable losses in terms of dollar value that would indicate the annual financial risk of the structure due to all possible seismic hazards. Khare et al. [12] used the quadruple integral formula for financial risk assessment of two reinforced concrete wall systems which were designed for ductility and damage avoidance. They established models for probable financial loss for two walls by combining nonlinear incremental dynamic analysis (IDA) results and seismic hazard recurrence relationship along with damage models developed based on experimental investigations. Bothara et al. [2] extended the fragility functions to seismic loss assessment of Unreinforced Masonry (URM) houses. The URM test models were dynamically tested on shake tables by applying various ground motions with peak ground accelerations up to 0.5 to 0.8 in longer and shorter directions respectively. The experimental results thus obtained were used for the development of fragility functions and expected annual loss for URM was calculated using quadruple integral equation given by Dhakal and Mander [5].
