A. Introduction: The subject of the building collapse is selected for the assignment as the phenomenon is correlated with the economic losses depending on the size of the building, duration of the collapse process and severity of the causing agent for the building collapse. Throughout the world hundreds of incidents are taking place of the building collapse on annual basis and their occurrence has resulted in economic and human losses(1). The subject is of special interest for the policy makers at the top hierarchical level at the central government’s office, for the non governmental agencies to evaluate and utilize the available data for making their strategies to cope with the emerging situations relating to the building collapse and for all other stakeholders to deal with the issue as per demand of their respective programs, strategies in line with their missions.
The current study will help in the understanding of the issue at its micro level and will fruitful in the formulation of future strategies to minimize the occurrence of building collapse through the adoption of necessary measures to reduce the happenings of the uncalled building collapses as is occurring in majority of the cases(2).
Buildings are the structures designed to support certain loads without any deforming impacts and maintain their originality with their accessories and fixtures. The structures have their different dimensions on the basis of their designs, purposes and locations(3). The loads are the weights of objects and the people who occupies or use the buildings to fulfill their material needs for a specific period of time. The loads of people and objects are called as live loads. The weight of snow and rain and the pressure of wind combine to form dead loads.
The strength of the buildings depends on the number of floors, rigidity in the structure and the designs of the buildings especially that of a roof. The impacts of weather and other physical conditions are regulated through the specific design of the roofs. In case of multi stories buildings the strength of the building is maintained through the use of pillars and beams with specific width and strength depending on the number of stories. In case of tall buildings, the roofs have little importance in the overall building structure and the support of such buildings is through the design and drawings with the use of proper material like steel, iron, aluminum, etc.
Tall buildings like long bridges are subject to catastrophic collapse with men and material loses depending on the agents and specific time of collapse(4). The buildings collapse are closely associated with the causes of collapse, severity of the cause, duration of the collapsing process, size of the buildings and the timings for the collapse process to occur.
The building’s collapse can be minimized with the use of specific techniques depending on the location of the building, age of the building, the external neighboring buildings and the agents responsible for the buildings’ collapse. The building collapse is the result of the happenings of the phenomenon due to the occurrence of one or more causes of the building collapse(5). These causes are the outcome of the failure of the observation of the building codes and design and drawings which are necessary and vital qualitative requirements for the physical health of the buildings for their existence in their original and designed shape.
The study is essential to understand the subject as the occurrence of the building collapse is having its economic significance for all the major stake holders to realign their programs to cater the future needs, to understanding the causes of building collapse relating to their structures, designs and height of the buildings. The identification of causes of the building collapse are necessary to understand the subject for evolving strategies at the top management level to minimize the prevailing trends, reducing the losses associated with the issue and to take preventive measures to reduce the degree of building collapse in future(6).
