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.

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 ...

EARTHQUAKES EFFECTS ON REINFORCED CONCRETE BUILDINGS

Reinforced Concrete Buildings In recent times, reinforced concrete buildings have become common in India, particularly in towns and cities. Reinforced concrete (or simply RC) consists of two primary materials, namely concrete with reinforcing steel bars. Concrete is made of sand, crushed ...
