Why do buildings collapse
Buildings are made in such a way that they can carry huge loads easily. But if the same buildings collapse then questions arise regarding its constructional structure and capacity of load bearing. Building collapse can take several lives and incur huge financial losses. Understanding the reasons why a building collapses can help us prevent the same. There can be many different reasons which are actively responsible for the collapse of a building like bad design, faulty construction, excessive pressure or load and a faulty foundation. It can also happen due to more than one reasons working in a combination.
It is the duty of the engineer to assess the load that a building has to carry every day. The purpose of a building helps the engineer draw plans accordingly. If the assessment is wrong or the engineer does not have sufficient or accurate information regarding the purpose of the house then there is a high chance that the building will collapse. Bad construction or several constructional mistakes can also lead to collapse of the building. To prevent this mistake, only good quality materials like steel and concrete should be used and the task of welding and constructing should be done by experts.
Natural calamities like excessive snowfall, earthquake and hurricanes can weaken a building or make it collapse. Faulty foundation can lead to the collapse of a building. No building can sustain the load it needs to bear if the foundation is not strong enough. There can be many small constructional flaws which accumulate the power to break the house and bring it to ruin over years. Sometimes a building is initially strong and stable but after long use and exposure to the elements of nature it weakens and ultimately breaks down.
