CHAPTER-2 REVIEW OF LITERATURE Ted Krauthammer et al. (2002) Conceded study on the development of progressive collapse analysis and damage valuation methodology of partially collapsed structures. The purpose of these expansions is to increase the safety of people in structures subjected to unusual loads. The developed analytical methods will support engineers to predict the type and range of probable progressive collapse in both the proposal stage and after existences. This is the main reason to connect a progressive collapse analysis with a structure identification procedure. This combined approach will be effective to prevent or minimize casualties and destruction caused by the unusual loads. Abhay A. Kulkarni and Rajendra R. Joshi. (2011)…show more content…
Then, a nonlinear static analysis procedure for existing building is offered. Evaluation of a six storey concrete structure is carried out and the result of this basic approach is compared with the calculation from a nonlinear dynamic procedure. They decided that a simple structural design standard including definitions of key or vital members in a structure is suggested. A simple quantitative nonlinear static procedure is suggested for analysing the progressive collapse potential caused by the removal of a…show more content…
Giriunas (2009) Presented a study on progressive collapse analysis of an present building. This research study investigates an actual structure’s potential to fail due to progressive collapse. Progressive collapse in a structure occurs when main structural load carrying members are removed unexpectedly, and the remaining structural elements cannot support the weight of the building and fail. This failure usually occurs in a domino effect and leads to a progressive collapse failure in the structure. The bombing of the Murray Federal Building in Oklahoma City is a classic example of progressive collapse failure. The preliminary bomb blast caused only 10% of the structure’s damage, and the resulting progressive collapse failure lead to 90% of the structure’s loss. This experiment involved testing of a steel building programmed for demolition in Northbrook, Illinois. The demolition team ripped out four selected columns from the building to pretend the sudden column removal that leads to progressive collapse. The structure was instrumented with strain gauges that recorded the change in strain in several structural members while the columns were removed. The author instrumented the beams and columns in the building, achieved the testing, and examined the recorded data. Future progressive collapse research orientations are also presented. The instrumentation of strain gauges for optimum results is deliberated, and column removal guidelines and linear displacement sensor
