Overseas Organizations’ Activities to Improve Seismic Performance of Masonry Houses in Developing CountriesAs a reference for BRI project formulation Satoru OBA Research Institute for Urban & Environmental Development, Japan
Research Background/Purpose • General perceptions • Traditional masonry houses have weaknesses in seismic resistance. • In spite of efforts to strengthen these houses, proposed techniques have not used widely. • Gathering information (through internet) on the activities of overseas organizations • concerning their achievements, encountered problem, and so on As a reference for the formulation of BRI project
Organizations Being Researched • International/Multi-National Organizations • Bi-Lateral Aid Agencies • Academic/Professional Societies • Universities/Research Institutes/ Information Centers • Others doing international activities • NGOs, Companies, Conferences, Networks Many Organizations are acting variously.
Project 1:Ceresis/GTZ/PUCP Project early-late ‘90s Ceresis: Regional Seismology Center for South America GTZ: German Agency for Technical CooperationPUCP: Pontifical Catholic University of Peru • Targeted Buildings • Adobe (existing) • Technical Solutions • Reinforcing walls • electro-welded wire mesh + cement mortal • Dissemination Methods • demonstration houses • manuals • DVDs • trainings/workshops
Project 2:IDRC/PUCP Project middle ‘80s-late ‘90s IDRC: International Development Research Centre (Canada) • Targeted Buildings • Adobe (new) • Quincha (new) mud +wood • Technical Solutions • Reinforcing walls • cane & wood + cement mortal • Dissemination Methods • demonstration houses • manuals • pamphlets/booklets • videos • trainings/workshops • radio shows
2003-ongoing Project 3:IAEE/EERI Tutorial (on the Web) IAEE: International Association for Earthquake Engineering EERI: Earthquake Engineering Research Institute (USA) • Targeted Buildings • Adobe (new & existing) • Other masonry buildings, etc. • Technical Solutions(Adobe) • Reinforcing walls • reinforcement with any ductile material • ring beam • buttresses & pilasters, etc. • Quality Management • materials & construction • Building Form Planning • squat & single story • small windows • regular & compact plan, etc. • Dissemination Method • tutorials (on the Web)
Project 4:World Bank/METU Project 2004 METU: Middle East Technical University (Turkey) • Targeted Buildings • Masonry (existing) • Technical Solutions • Reinforcing walls • scrap-tires • Dissemination Methods • posters • pamphlets/booklets • website • trainings/workshops
focusing on 2001-ongoing activities Project 5:NICEE/IITK Activities NICEE: National Information Center of Earthquake Engineering(India) IITK: Indian Institutes of Technology, Kampur • Targeted Buildings • Masonry (new & existing) • Technical Solutions • Reinforcing walls • ring beam • protecting window corners, etc. • Quality Management • materials & construction • Dissemination Methods • Earthquake Tips(on website; in newspapers & journals) • trainings/workshops • acquiring & disseminating latest professional information • e-conference
Research Findings 1Substantial Accumulation of Efforts on Technical Development & Dissemination • Various techniques have been developed. • Their seismic performance has been proved. • Affordability and technical simplicity have been sought. • e.g., scrap-tires = US$100, wire mesh = US$400/housing unit • Various methods/tools have been used to disseminate. • methods/tools used in the five examples • translation of useful foreign manuals (e.g., IIEA 1986 Manual) • demonstration of improvement effect (e.g., UNCRD shake table demo) • international networks for collaboration/information sharing (World Housing Encyclopedia) However, new techniques haven’t been used as expected.
