## Category : Earthquake Engineering

Earthquake engineering deals with the study of earthquake forces and its effects on the buildings and structures, so that earthquake resistant buildings and structures can be built to prevent loss of life and property during earthquakes.
This section deals with the study of forces of earthquakes, magnitude and energy released, earthquake resistant design technique, damage caused due to earthquake on structures, design philosophy, architectural features, ground shaking, seismic zones, base isolation method, earthquake resistant design philosophy, guidelines, and estimation of damage and collapse of structures and buildings.

## Seismic Design of Retaining Wall

Seismic design of retaining wall is considerably complicated problem in which assumptions have to be considered in order to make indeterminable issue solvable employing theory of statics and differential calculus. The computation of each static and dynamic pressure acting on retaining ...

## Performance and Behavior of Masonry Structures during Earthquakes

Masonry structures are most vulnerable during earthquake. Performance and behavior of masonry structures during earthquakes is discussed in this article. Many human fatalities have depended on masonry constructions from the past. The condition is same at the present. As the main ...

## Ductility of Building Structures for Earthquake Resistant Design

Ductility for earthquake resistant design is important for buildings, structures and building materials. Ductility and its importance in design is discussed. To understand the importance of ductility in influencing the building performance, it is essential to know what is ductility. Ductility ...

## WHAT IS TUNED MASS DAMPER AND ITS APPLICATIONS?

A tuned mass damper is a device mounted in structures to prevent discomfort, damage, or outright structural failure caused by vibration. They are used in high rise buildings to prevent failure of buildings during earthquakes. They are also known as an active mass ...

## BASE ISOLATION METHOD IN BUILDING

Base Isolation Method in Building Construction Conventional Construction Practice assumes Fixed Base StructuresThe Dynamic Characteristics of Fixed Base Structures are determined by the general characteristics of the structural system The Designer can only slightly adjust those Dynamic Characteristics As a ...

## PERFORMANCE OF VARIOUS TYPES OF BUILDINGS DURING EARTHQUAKE

Different types of buildings suffer different degrees of damage during earthquakes and the same has been studied here. 1. MUD AND ADOBE HOUSES: Unburnt sun dried bricks laid in mud mortar are called adobe construction. Mud houses are the traditional construction, ...

## IMPROVING EARTHQUAKE RESISTANCE OF SMALL BUILDINGS

The earthquake resistance of small buildings may be increased by taking some precautions and measures in site selections, building planning and constructions as explained below: 1. Site Selection for small buildings: The building constructions should be avoided on (a) Near unstable embankments (b) On ...

## CALCULATE EARTHQUAKE FORCES ON BUILDINGS AND STRUCTURES

Earthquake resistant design of structures have become integral part of structural design of any structure. The guide to earthquake resistant design of building and structures are given by IS1893 – 2002 in India. Here we will talk about how to ...

## DAMPERS FOR SEISMIC RESISTANT STRUCTURES

Seismic Dampers Seismic Dampers are used in place of structural elements, like diagonal braces, for controlling seismic damage in structures. It partly absorbs the seismic energy and reduces the motion of buildings. Types of Seismic Dampers:Viscous ...

## TYPICAL DAMAGE AND COLLAPSE OF RC BUILDINGS

The following types of damage are quite common in reinforced concrete buildings: 1. Sliding of roofs off the supports Where the beams simply rest on walls or columns, they are bound to slide, when the earthquake intensity exceeds the ...
