Earth Quake Resistant Structures
EARTH QUAKE RESISTANT STRUCTURES

ABSTRACT
Earthquake is the shaking of the ground caused by the sudden breaking and shifting of large sections of Earth 's rocky outer shell. Earthquakes are among the most powerful events on earth, and their results can be terrifying. Earthquakes in general does not kill people directly. Instead, many deaths and injuries result from the collapse of buildings, bridges, and other structures. We cannot prevent natural disasters from striking, but we can prevent or limit their impact by making buildings strong enough to resist their destructive forces. This can be achieved by earth quake resistant structures. In the case of earth quakes, it is possible to neutralize their harm by applying basic engineering and planning principles that are inexpensive. This paper deals with the explanation of basic engineering and planning principles to be taken into account during the construction of earth quake resistant structures. This paper mainly deals with (i) the various types of failures that are caused due to the vibrations during the earthquakes (ii) analysis of the failures and (iii) solutions for overcoming failures.

Key words: Earth quake resistant structures, Shear joint failures, Structural failures, Non Structural failures Site failures, Foundation failures, Lateral force resisting system.

1. INTRODUCTION Earthquake is the shaking of the ground caused by the sudden breaking and shifting of large sections of Earth 's rocky outer shell. Earthquakes are among the most powerful events on earth, and their results can be terrifying. The force of an earthquake depends on how much rock breaks and how far it shifts. Powerful earthquakes can shake firm ground violently for great distances. During minor earthquakes, the vibration may be no greater than the vibration caused by a passing truck. In order to construct earth quake resistant structures we need to analyze the way in which buildings respond towards the vibrations

    A ‘hazard’ can be defined as a geophysical process operating within the lithosphere, atmosphere, hydrosphere or biosphere which could potentially lead to the loss of human life or property. However, an earthquake only becomes hazardous and therefore needs management if it occurs within close proximity to a vulnerable population. To some extent, any human settlement around the world situated close to or on top of an area of seismic activity is vulnerable. However, not all nations suffer equal devastation.…

    Even with the city of Los Angeles have strong structured building to deal with the harms and hazards that come with having earthquakes. Many would call these structures earthquake resistant. According to building codes, earthquake-resistant structures are projected to endure the largest earthquake of a certain chance that is likely to occur at their location. This means the loss of life should be decrease by averting collapse of the buildings for rare earthquakes while the loss of functionality should be limited for more frequent ones.…

    Earthquakes in Los Angeles, California can be devastating to people, cities, and the landscape. Earthquakes can cause millions if not billions of dollars of damage in only a matter of a few minutes. The more populated the area where the earthquake strikes or the earthquakes epicenter, the more the disaster can occur. Buildings are constructed to an earthquake code, but that does not mean there can be no damage to them. Brick faces can fall, windows can shatter, and structures can become unsafe. Bridges can buckle and with that their support beams and vital components can ultimately fall down to the ground in a pile of twisted steel. Water and sewage pipes can rupture filling buildings with water and poisonous…

    Granted, the entire cascade of events associated with this natural disaster was very unfortunate and disheartening. But, the Haitian nation was simply not adequately prepared to prevent the effects of the earthquake from reaching as far as they did. As a result, a mind boggling question has been raised: could simple efforts have caused this catastrophe to have been less catastrophic? This research topic is being explored by building officials, architects, and designers worldwide who seek to lessen earthquake-related effects on society (Jain). As living standards rise and urbanism spreads in the modern world, the potentiality for earthquake-related catastrophe has spiked. Therefore, cautious steps must be taken to decrease the level of all earthquake-related catastrophes in developing countries while technology behind earthquake resistant architecture is reengineered and…

    Economic cost was high with losses estimated at $40 billion. The earthquake severely tested building codes, earthquake-resistant construction and emergency preparation and response procedures. The experience confirmed many of the lessons learned from past earthquakes, exposed weaknesses in the society’s generally resilient fabric, and produced many surprises about the levels and consequences of strong ground shaking. Near the epicenter in the San Fernando Valley, well-engineered buildings withstood violent shaking without structural damage. However, numerous structural failures throughout the region were evidence of significant…

    For decades, the goal of seismic engineers has seemed straightforward: Prevent building collapse. And so they add steel braces to a skyscraper’s skeleton or beefier rebar to concrete shear walls. After absorbing the brunt of seismic shaking, however, the compromised structures often must be demolished. “The building, in a sense, sacrifices itself to save the occupants,” says Gregory Deierlein, a Stanford University civil and environmental engineer. A team Deierlein led with Jerry Hajjar, a Northeastern University engineer, hopes to change that, designing a system that protects both people and the structures they live and work in.…

    If the building or structure is a normal single storey, then any normal portal frame or other steel framed building, if the design and construction is competently done, will be resistant to Earthquake loads. If it is to have 2 or more stories, more needs to be done to ensure its survival in an earthquake. As with the roof, the floors should be made as light as possible. The first way to do this is to use traditional timber joists and timber or chipboard or plywood flooring. If this is done it is vital that the timber joists are firmly through bolted on the frames to avoid them slipping or being torn off. The frame needs them for stability and the floor must never fall down. A better alternative is to substitute light gauge steel Zeds for the timber joists. These can span further and are easier to bolt firmly to the framework. Then, floor-boards or tongue-and-groove chipboard can easily be screwed to the Zeds. However in Hotels, Apartment buildings, Offices and the like, concrete floors may be needed. In such cases we should reduce…
