Tips to design buildings that can resist Earthquakes

1. Tips to design buildings that can resist Earthquakes Earthquake resistant design of buildings depends upon providing the building with strength, stiffness and inelastic deformation capacity which are great enough to withstand a given level of earthquake- generated force. This is generally accomplished through the selection of an appropriate structural configuration and the careful detailing of structural members, such as beams and columns, and the connections between them. But more advanced techniques for earthquake resistance is not to strengthen the building, but to reduce the earthquake-generated forces acting upon it. 1.More Strength is much important When designing earthquake-resistant buildings, safety professionals recommend adequate vertical and lateral stiffness and strength – specifically lateral. Structures tend to handle the vertical movement caused by quakes better than the lateral, or horizontal, movement. Without considering earthquakes, professionals still focus on a building’s vertical stiffness and strength as it has to support itself. However, earthquakes introduce new directional forces that may not be prepared for. Buildings will shift left and right during the event, and, if not built properly, will quickly destabilize. 2.Regularity This characteristic refers to the movement of the building when pushed in lateral directions. Safety professionals and building designers want the building to move equally so as to dissipate the energy without placing too much force on one side or another. If a building is irregular, then weaknesses will become apparent when the building sways. The weakness will compromise and the structure will see concentrated damage – which compromises the structure as a whole. 3.Redundancy Possibly one of the most important safety characteristics when designing for safety, redundancy ensures there are multiple strategies in place in case one fails. These can potentially add to the building cost, but redundancies prove their worth if/when a natural disaster such as an earthquake occurs. Safety professionals advise equally distributing mass and strength throughout the structure so strength isn’t solely reliant on one factor. 4.Foundations A stable foundation is a major characteristic of building a large structure regardless of natural disaster risks. It is critical for a building’s long-term survival, and a stronger foundation is necessary to resist an earthquake’s powerful forces. Different areas have unique foundational characteristics that define how a structure’s base needs to be reinforced. Professionals have to closely observe how the ground reacts and moves before building. Buildings designed to withstand violent earthquakes have deep foundations and driven piles. To stabilize these drastic measures, the foundations are connected so they move as a unit.

2. 5.Shock Absorption: Similar to the shock absorbers used in vehicles, buildings also makes use of this technology. This earthquake resistant technology helps buildings slow down and reduce the magnitude of vibratory motions. Ideally shock absorbers should be placed at each level of the building – one end attached to the beam and the other end to the column. Each comprises a piston head that moves inside a cylinder full of silicone oil. During earthquakes, the horizontal motion of building will make the piston push against the oil, transforming mechanical energy from the quake to heat. Seismic Engineering is a very complex and constantly evolving. Seismic structural assessment is a powerful tool in Earthquake Engineering that uses detailed modeling of the structure in conjunction with structural analysis to get a better understanding of the building’s resistance. Retrofitting older structures with enhanced designs or materials is as important as rebuilding new structures from scratch. The ultimate goal of Earthquake Civil Engineering is to save lives so that the buildings don’t collapse and allow inhabitants to escape in a timely manner.
