The GOI envisages ‘Housing for All’ - a scheme for creationof 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 Secretaryof the Committee.

Background

Department of Civil EngineeringIndian Institute of Technology Kanpur, KANPUR

It is envisaged that the Technology Sub-mission, MoHUPAand States would also partner with willing IITs, NITs andPlanning & 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?

Background

Important Performance Considerations

Requires creation of houses on a massive scale

Wide range of structural materials and components may beused to create any single housing unit

The quality and performance cannot be allowed to fallbelow an acceptable level for materials, components or theunit/system

Issues such as workmanship in putting the componentstogether is an important aspect too

Given the massive scale of housing units, it is important thatcertain technical tasks are taken up on priority and a basicframework for testing of components and units be madeavailable for field engineers

Development of draft protocol for testing of structural components and

systems for use in schemes under ‘Housing for all’ project of the

Project Proposal

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, cyclonicstorms etc.).

Though lot of reference materials available, the tests reportedcarried out under different conditions on ‘specimens’of

different sizes,

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

Aspects Highlighted

Main GoalTo develop protocols for structural testing of components ofhousing units and models of prototype housing units withemphasis on natural disasters (earthquakes, tsunamis,cyclonic storms, land slides etc.).

Points to cover Items that needed to be testedEnvironment 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 protocolShare results with field engineers and state agencies though

workshop, websites etc. Identify new research areas that need attention for this

purpose

Basically create a ‘menu card’approach

• Freedom to the ‘user’to decide theapplied loads

• Freedom to decide the ‘expected performance’

Methodology1. 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

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 in-plane and out-of-plane bending, cyclic loading etc.

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. Bajpai (Co-PI), IIT Kanpur • Professor K.V.
