Earthquake Resistant Consultancy

Ravindra Prakash and Associates are the leading earthquake and structural engineering consultants having provided earthquake resistant design and seismic retro-fitting/strengthening to more than 1000 important structures and buildings in the country.

The firm has to its credit, the successful handling of multi Million Dollar projects. It has won acclaim & awards from satisfied clients. The firm has a very modern outlook & participates greatly in Infrastructure building. Great emphasis is laid on the quality of Drafting and Technical Drawings. The computer System available with the firm is capable of tackling even the most complex of engineering problems.

Apart from providing complete Earthquake Proof civil & structural designs & drawings for multi-storied buidings, industries, foundations and Industrial sheds. Ravindra Prakash & Associates are experts in Seismic Retro-fitting & strengthening of old structures as well as installing new Machinery & Equipments of increased capacity on old foundations to achieve economy & saving of the time.

Mr. Ravindra Prakash is one of the senior most Earthquake and Structural Engineers of the country. Heir of a renowned Zamindar family of northern India, Mr. Prakash graduated in Civil engineering in 1970 and majored in earthquake engineering with specialisation in Structural Dynamics in 1973 from IIT-R (formerly University of Roorkee) and served there, first as lecturer and than as Reader till 1989 where after he resigned to establish his Eartuquake & Structural Engineering Consultancy under the name and style of Ravindra Prakash and Associates. Mr. Prakash is structural consultant to a large number of Government, semi-government and corporate organizations. Aesthetics, economy, ease of construction and simplicity of solution of even the most complex of engineering problems are the hall marks of his work. Mr. Ravindra Prakash is a keen Golf & Bridge player. He is a voracious reader & thinker. An audio CD of his poems has also been released.


  • Buildings or structures are usually designed to bear only vertical loads. However, in the event of an earthquake, The ground shakes to & fro. This motion of the ground, imposes an additional horizontal load on the Building which it is unable to withstand unless specifically so designed; hence the damage.
  • Surprisingly, the additional cost to make a building/structure earthquake resistant is very low, usually about 5% of the structural cost of the building which comes out to be not more than 1-2% of the total cost of the building.
  • Earthquakes don't kill People, Buildings do.

Earthquakes are likely, knowing how to build can help reduce injury, loss of life, and property damage during an earthquake.

An earthquake-resistant building has a number of special structural features. Interior support walls called shear walls, made of reinforced concrete, strengthen the structure and help resist rocking forces. Shear walls in the center of a building form a shear core. Cross-bracing reinforces walls with diagonal steel beams. Base isolators act as shock absorbers, and a moat allows a building to sway.


How to build?

A number of methods have been developed to build earthquake-resistant structures. These techniques range from extremely simple to fairly complex. For small- to medium-sized buildings, the simpler reinforcement techniques include making the structure ductile when subjected to earthquake. This ductility is achieved using properly placed reinforcement and providing support walls called shear walls. Shear walls, made of reinforced concrete (concrete with steel rods or bars embedded in it), help strengthen the structure and help resist rocking forces.

Sometimes, the buildings are protected using medium-sized devices that act like shock absorbers between the building and its foundation. These devices called base isolators, are usually bearings made of alternate layers of steel and an elastic material such as synthetic rubber. Also base isolators absorb some of the sideways motion that would otherwise damage a building.


Seismic Retrofitting


Seismic Retrofitting means providing Earthquake Resistance to an old building. Retrofitting also allows a building to withstand much greater earthquake forces then those for which it was originally designed with much less structural damage. Retrofitting also means making a building re-serviceable and reusable after it has suffered moderate to major structural damages during an earthquake. A Seismic Retrofitting generally costs between 1% and 3% of a home's value.

However it is only a one time cost.
