1 Development of Draft Protocol for Testing of Structural Components and Systems Sponsored by Ministry of Housing and Urban Poverty Alleviation Government of India (MoHUPA) Samit Ray-Chaudhuri Associate Dean, Physical Infrastructure & Associate Professor, Department of Civil Engineering IIT Kanpur June 24, 2016

2 Department Background of Civil Engineering Indian Institute of Technology Kanpur, KANPUR The GOI envisages Housing for All - a scheme for creation of houses on a massive scale Ministry of Housing and Urban Poverty Alleviation (MoHUPA) constituted a Technology Sub-Mission under the chairmanship of Joint Secretary (HFA), MoHUPA comprising of 16 members represented by State Govt. Academicians and Experts Executive Director, BMTPC (Building Materials & Technology Promotion Council) is the Member Secretary of the Committee.

3 Department Background of Civil Engineering Indian Institute of Technology Kanpur, KANPUR It is envisaged that the Technology Sub-mission, MoHUPA and States would also partner with willing IITs, NITs and Planning & Architecture institutes for Developing technical solutions Capacity building and Handholding of States and Cities Are we focusing on Low-cost Housing? Is it just constructing houses for people?

4 Important Performance Considerations Requires creation of houses on a massive scale Wide range of structural materials and components may be used to create any single housing unit The quality and performance cannot be allowed to fall below an acceptable level for materials, components or the unit/system Issues such as workmanship in putting the components together is an important aspect too Given the massive scale of housing units, it is important that certain technical tasks are taken up on priority and a basic framework for testing of components and units be made available for field engineers

5 Project Proposal Development of draft protocol for testing of structural components and systems for use in schemes under Housing for all project of the Government of India Prof. Sudhir Misra, Dept of CE (PI) Prof. Samit Ray Chaudhuri, Dept of CE (Co-PI) Dr. KK Bajpai, Dept of CE (Co-PI)

6 Urgent need to develop protocols for structural testing of Components of housing units and Models of prototype housing units with emphasis on natural disasters (earthquakes, tsunamis, cyclonic storms etc.). Though lot of reference materials available, the tests reported carried out under different conditions on specimens of different sizes, Aspects Highlighted prepared under varying conditions, etc. making a direct comparison of results difficult Data on composite units are very limited Problems of accounting for the difference on account of workmanship makes any comparison difficult

7 Main Goal To develop protocols for structural testing of components of housing units and models of prototype housing units with emphasis on natural disasters (earthquakes, tsunamis, cyclonic storms, land slides etc.). Points to cover Items that needed to be tested Environment and structural loading conditions for testing Identification of an appropriate test method / protocols Identification of the required performance parameters Identify the laboratories / institutions that can carry out the testing as per the laid down protocol Share results with field engineers and state agencies though workshop, websites etc. Identify new research areas that need attention for this purpose

8 Department of Civil Engineering Indian Institute of Technology Kanpur, KANPUR Basically create a menu card approach Freedom to the user to decide the applied loads Freedom to decide the expected performance

9 Methodology 1. Review of existing state-of-the art practice Study existing structural testing protocols being used worldwide (IS, ERUO, FEMA, ATC, ASTM, etc) for different kinds of construction Study test standards and list recommended and relevant test Make draft structural testing protocols 2. Disseminate knowledge through workshop Diversity of workshop attendees: Academics, Industry, Government engineers Discuss draft structural testing protocols Workshop recommendations 3. Propose structural testing protocols as per the requirements of Housing for ALL project

10 Draft protocols for testing of structural components and systems For Materials: Test standards for different construction practices are being compiled (e.g. testing of physical properties of different types of bricks like burnt clay bricks, fly ash bricks, hollow & solid concrete blocks, AAC blocks, etc. for masonry constructions) For Systems & Components: Test standards for performance of different construction practices e.g. masonry walls subjected to inplane and out-of-plane bending, cyclic loading etc.

11 Draft protocols for testing of structural components and systems Subject: e.g., Bricks, beam-column joint Brief title of the test Step-by-step procedure for testing including schematic diagram and pictures Data collection and processing issues Result template Acceptability issues Examples of different test results showing acceptable and to be rejected samples

12 Task force To accomplish the objectives through a task force comprising of all stakeholders - academics, engineers, regulators, users Following Task Force (tentative) has been constituted: Professor Sudhir Misra (PI), IIT Kanpur Professor Samit Ray Chaudhuri (Co-PI), IIT Kanpur Dr. K.K.
