Earthquake engineering deals with the study of earthquake forces and its effects on the buildings and structures.

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 ...

SAFE DESIGN AND CONSTRUCTION OF MULTISTOREY RCC BUILDINGS

MULTISTOREY REINFORCED CONCRETE BUILDINGS DESIGN A large number of reinforced concrete multistoreyed frame buildings were heavily damaged and many of them collapsed completely in Bhuj earthquake of 2001 in the towns of Kachchh District (viz., Bhuj, Bhachao, Anjar, Gandhidham and Rapar) ...

PERFORMANCE BASED EARTHQUAKE RESISTANT DESIGN

The performance-based seismic engineering (PBSE) produces structures with predictable seismic performance. This approach is not new. Using this approach / model Turbine, Airplanes & Automobiles are made. In these applications one or more prototype are built and subjected to extensive ...

I.S CODES ON EARTHQUAKE RESISTANT BUILDING DESIGN

Earthquake resistant building design guidelines are provided by set of Indian Standard codes (IS Codes). After observing Indian earthquakes for several years Bureau of Indian Standard has divided the country into five zones depending upon the severity of earthquake. IS ...

Seismic Design of Multi-Storied RCC Buildings

Reinforced concrete multi-storied buildings are very complex to model as structural systems for analysis. Usually, they are modeled as two-dimensional or three-dimensional frame systems using finite beam elements. For evaluating stiffness matrix of beam elements, the properties required are ...

EARTHQUAKE MAGNITUDE AND ENERGEY RELEASED

RELATION BETWEEN EARTHQUAKE MAGNITUDE AND ENERGY RELEASED An earthquake of magnitude 8.2 releases 1000 times more energy than the earthquake of magnitude of 6.2 and 32 times more than the magnitude of 7.2. A table below gives the relation between magnitude change ...

EARTHQUAKE RESISTANT DESIGN TECHNIQUES

The conventional approach to 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 ...

SOURCES OF EARTHQUAKE DAMAGE

Vibration of the structure in response to ground shaking at its foundation is the concern of the structural engineer, and which is taken into account by codal provisions of the different seismic-resistant design codes. However, these codes do not include ...
