Osdag Beta Launch, June 2017


Osdag is a cross-platform free and open source software for the design (and detailing) of steel structures, following the Indian Standard IS 800:2007. It allows the user to design steel connections, members and systems using an interactive graphical user interface. The interactive GUI provides a 3D visualisation of the designed component and creates images for construction/fabrication drawings. The design is typically optimised following industry best practices.

A beta version of Osdag was released on 21-Jun-2017.


The launch of Osdag beta was held in the Seminar Room, Dept. of Civil Engineering, IIT Bombay. The chief guest invited for this occasion was Mr. Sushim Banerjee, Director General, Institute for Steel Development and Growth (INSDAG), Kolkata. Other guests included senior representatives from IIT Madras, Centre of Excellence in Steel Technology (CoEST, IIT Bombay), FOSSEE (IIT Bombay), MN Dastur & Co, Tata Consulting Engineers Ltd, Consulting Engineers’ Association of India (CEAI), Steel Authority of India Ltd (SAIL), JSW Steel, Construma Consultants, Aker Powergas Ltd, L&T Construction, Shastra University, MIT Aurangabad, Dept. of Civil Engineering, IIT Bombay, etc.

Prof. K.V. Krishna Rao, Head of the Department of Civil Engineering, offered Mr. Sushim Banerjee to release the installation DVD of Osdag beta. Mr. Banerjee also inaugurated the updated Osdag website <osdag.fossee.in>. The installers of Osdag for Ubuntu Linux and Windows operating systems were made available to general public. The released version of Osdag has four shear connection modules.

The chief guest presented how a software like Osdag can contribute to the growing steel market in India. Prof. Siddhartha Ghosh (PI, Osdag) gave an overview of Osdag, its objectives, features, and future plans. Jayant Patil from the Osdag team presented a demonstration of the software, highlighting how it is useful both for a novice user and an expert in steel design. Prof. Prabhu Ramachandran (PI, FOSSEE, IITB) gave an overview of the free and open-source concepts in software development. Prof. K. Narasimhan (Prof.-in-charge, CoEST, IITB) presented the perspectives of the Ministry of Steel, GoI, in terms of infrastructure development. Mr. Manas M. Ghosh (INSDAG) shared his experience of using Osdag and how it can be beneficial to the academia and industry. Mr. Somnath Mukherjee (MN Dastur & Co) emphasized the importance of connection design and its very poor state in the Indian steel construction industry. He also shared his excitement of having a software like Osdag. Expert reviewers of Osdag, including Prof. S.R. Satish Kumar (IIT Madras), Prof. Meera Raghunandan (IIT Bombay), Mr. Yogesh Pisal (Aker Powergas Ltd), Dr. Harshvardhan Subbarao (Construma Consultants), gave brief talks.
