How can a building resist damage from an earthquake?

How can a building resist damage from an earthquake?

To withstand collapse, buildings need to redistribute the forces that travel through them during a seismic event. Shear walls, cross braces, diaphragms, and moment-resisting frames are central to reinforcing a building. Shear walls are a useful building technology that helps to transfer earthquake forces.

What are the major causes of damages in buildings due to earthquake?

For reinforced concrete (R/C) buildings, inappropriate design such as soft and weak stories, strong beam–weak column, short column, hammering, unconfined gable wall and in-plane/out-of-plane movement of the walls causes damages. These are the main reasons.

What is the problem of earthquakes?

The primary effects of earthquakes are ground shaking, ground rupture, landslides, tsunamis, and liquefaction. Fires are probably the single most important secondary effect of earthquakes.

What do you need to know about earthquake resistant construction?

Concept of Earthquake Resistant Design of RC structures Actual Construction Practice Construction practice – Beam, column, foundation, walls and roofs Geotechnical considerations –Earthquakes do not kill, unsafe buildings do

What are the factors that affect earthquake resistance?

There are three main factors when assessing the earthquake resistance of a building: The extent of maintenance of the building over time, including an assessment of the level of wear and tear in the building since completion of construction and/or refurbishment. Are all buildings built prior to 1981 less earthquake resistant than newer ones?

How is the behavior of a building affected by an earthquake?

The behavior of a building during ground vibration is a function of the nature of foundation soil and natural period of vibration of the structure, which depends on the material used in construction, its form, size, and mode of construction etc. The structure also gets affected with the duration & intensity of the earthquake.

What makes a building earthquake resistant in Nepal?

Any discontinuity in the load path caused by discontinuous column, floating columns, vertical setbacks causes sudden leap in earthquake forces resulting in poor performance during earthquake. Such situation should be avoided as much as possible and should have uniform stiffness to make it earthquake resistant. 2. Proportion of Building
