Buildings frequently collapse when the weight exceeds the building's strength, which occurs when additional stories are added. Furthermore, the building's strength should be checked at various phases of construction. Rainfall is a natural component that causes building collapses, particularly in India. However, there are other factors such as use of inferior materials, lack of maintenance, and vandalism that can also cause buildings to collapse.
Building collapses are common occurrences in developing countries like India. Many Indians believe that buildings will not collapse, because they view them as solid structures. This misconception could be the reason why so many people are killed or injured every year in building collapses.
The number of deaths due to building collapses is high because people don't know how strong certain buildings are. Sometimes, families think that their dead loved ones can't be recovered because the building was collapsed, but this is false. The bodies can be retrieved if sufficient attention is given to the recovery process.
Also, buildings do not necessarily have to collapse in order to kill someone. For example, they may fall on someone who is inside them, such as when a builder works at night and falls off of his/her roof while asleep.
Finally, let us remember the words of Che Guevara when asked about his favorite method of revolution: "To build a new world, we need new methods".
A building collapse is the structural breakdown of a reinforced concrete building caused by an overload higher than the capacity of the construction. Structural failure occurs when structural materials are reversed at their strength limit for a variety of causes. In buildings, these causes include deterioration due to age or environmental conditions, such as humidity, heat, and cold. Other causes include damage from heavy loading or an accident. When a structure fails suddenly without warning, it is said to have collapsed.
Building collapses are one of the most common causes of death in developing countries. The lack of adequate safety measures, such as building codes, hazardous material regulations, and labor laws, results in deaths and injuries every year. In developed countries, building collapses are also common but usually due to natural disasters or acts of violence. There were about 200 fatal building collapses in the United States between 2000 and 2003.
The danger of building collapses exists for everyone who enters a damaged building. People who escape unharmed may carry diseases with them that could harm others. For this reason, building collapses are considered to be one of the most dangerous types of disasters. The degree of danger depends on several factors such as how much damage there is, what type of damage there is, where the damage is located, and how long after the incident was there time for people to leave the building.
Excessive Weight: Buildings might collapse merely because they are required to hold an excessive amount of weight. Similarly, improvements to an old structure might result in a collapse if the structure was not intended to sustain the added weight. For example, an enlargement to a building's roof area might cause it to fail when added to its existing weight load.
Violent Blows: A building can be weakened by a single violent blow. This may happen if a heavy object falls on a small section of a building's exterior wall or floorboard. The impact could shatter some of the walls or floorboards, which would allow other parts of the wall or flooring to give way too.
Old Age: A building can also collapse due to old age. Over time, the wood frame of a building will shrink and swell with changes in temperature. This movement is called "bowing" and it occurs whether or not you notice it. As bowering progresses, the walls of the building become weak and could lead to collapse.
Fire: Fire can also cause structural damage and even collapse buildings. The type of damage depends on how fire affects different parts of the building. If flames touch any fuel such as gasoline or wood, it will burn quickly and might cause total destruction of the building. On the other hand, if fire does not reach any fuel, it will die down over time.
