What is earthquake engineering subject?

Earthquake engineering is an interdisciplinary scientific area, it identifies and solves problems associated with occurrence of earthquakes, with the goal of reducing seismic risks to socio-economically acceptable levels, it requires as it does knowledge and development from geology, seismology, geotechnical, marine …

What do Earthquake Engineering do?

Earthquake engineers investigate the reasons why infrastructure and buildings fail during earthquakes and then apply their knowledge to planning, designing, constructing, and managing earthquake-resistant structures and facilities.

What is earthquake engineering necessity?

Earthquake engineering is the science of the performance of buildings and structures when subjected to seismic loading. One of the most important aims of earthquake engineering is the proper design and construction of buildings in accordance with building codes, so as to minimize damage due to earthquakes.

What is earthquake load in civil engineering?

Earthquake load acts over the surface of a structure placed on ground or with adjacent building. Earthquake load depends on the following factors, 1) Seismic hazard, 2) Parameter of the structure and 3) Gravity load. It will be used to plan the buildings in such a way to reduce the damage caused by the earthquake.

When did earthquake engineering start?

In the name of the Earthquake Engineering Research Institute, the words “earthquake engineering” originally meant, when the organization was incorporated in California as a non- profit organization in the USA November 4, 1948 and began operations in 1949, the application of engineering to the earthquake problem.

What are earthquake forces?

Earthquake forces are called lateral forces because their predominant effect is to apply horizontal loads to a building. Although earthquake waves do impart a vertical component of force to buildings, the weight of the building normally provides sufficient resistance.

What earthquake loads on structure?

Seismic loading is one of the basic concepts of earthquake engineering which means application of an earthquake-generated agitation to a structure. It happens at contact surfaces of a structure either with the ground, or with adjacent structures, or with gravity waves from tsunami.

What means imposed load?

Imposed load is defined as the load that is applied to the structure that is not permanent and can be variable. In Eurocode phraseology, it is described as a ‘quasi-permanent variable action’.

What are the main principles of engineering?

Engineering Principles

• Testability.
• Maintainablity.
• Integrity.
• External integration is well defined.
• Ethics.
• Management.

What is the relation of earthquake engineering with geology?

Engineering Geology and Seismic Engineering Services Some areas of focus are structural geology, the nature and behavior of rock and soil materials as they occur in natural ground, and the relationship that those rocks and geologic materials may have on development and human processes.

What are three factors that influence the magnitude of the earthquake load on a structure?

The wind load is an external force, the magnitude of which depends upon the height of the building, the velocity of the wind and the amount of surface area that the wind “attacks.” The magnitude earthquake load depends up the mass of the structure, the stiffness of the structural system and the acceleration of the …

What is earthearthquake engineering?

Earthquake engineering is a multi-phased process that ranges from the description of earthquake sources, to characterization of site effects and structural response, and to description of measures of seismic protection.

What is the job description of Earthquake Engineering?

Earthquake engineering. Earthquake engineering is an interdisciplinary branch of engineering that designs and analyzes structures, such as buildings and bridges, with earthquakes in mind. Its overall goal is to make such structures more resistant to earthquakes. An earthquake (or seismic) engineer aims to construct structures

What is seismic design and why is it important?

Seismic design is based on authorized engineering procedures, principles and criteria meant to design or retrofit structures subject to earthquake exposure. Those criteria are only consistent with the contemporary state of the knowledge about earthquake engineering structures.

What is the scope of Earthquake Engineering in the future?

However, the tremendous costs experienced in recent earthquakes have led to an expansion of its scope to encompass disciplines from the wider field of civil engineering, mechanical engineering, nuclear engineering, and from the social sciences, especially sociology, political science, economics, and finance.
