INTRODUCTION:

 
Structural Engineering Research Centre (SERC), Chennai, India is one of the national laboratories under the Council of Scientific & Industrial Research (CSIR), India. SERC has built-up excellent facilities and expertise for the analysis, design and testing of structures and structural components. Services of SERC are being extensively used by the Central and State Governments and public and private sector undertakings. Scientists of SERC serve on many national and international committees and the Centre is recognised at the national and international levels as a leading research institution in the field of structural engineering. SERC has recently been certified as ISO:9001 quality institution.
 
R & D EFFORTS AND AREAS AT SERC:
 
Research and Development efforts at SERC deal with development of improved analysis, design and construction techniques for different types of complex structures such as shell roofs, transmission line and microwave towers and other tower-like structures, ships, offshore structures and machine foundations. A number of time and cost saving precast construction techniques and products have been developed by the Centre. High strength deformed bars, funicular shells, fibre reinforced concrete manhole covers, ferrocement water tanks, service core units, etc., developed by the Centre have been extensively used in many organizations in the country. Over the years, several general purpose computer software packages have been developed for computer-aided analysis, design and drafting of various structures and structural components.
