The Commonwealth Network for Earthquake-Resistant Construction in Developing Countries Vol. Here are a few observations of postgraduate reinforced concrete and masonry research at the Civil Engineering Department, Indian Institute of Technology, Kanpur. Here, and elsewhere, earthquake engineering research was very well suited to local conditions.
Researchers are to be congratulated on their efforts.
After investigating the load carrying capacity of bare frames without infill, various types of infills are being tested in models built to one third of full scale. The programme is attempting to quantify the strength of typical infill frames and to suggest a design methodology. The following observations can be made from the test shown in Fig.1. Due to a deliberately low mortar strength, horizontal sliding along brick courses has occurred before any significant diagonal compression struts have formed. After cracking, the infill strength is minimal.
