Seismic Hardening of Unreinforced Masonry Walls through a Surface Treatment.

摘要

The primary objective of this project was to determine the feasibility of using a coating or surface treatment to achieve seismic hardening of unreinforced masonry walls. This was accomplished by assembling available information on methods of reinforcing existing masonry which are now in use,by reviewing available test data of unreinforced masonry,by researching available coatings,by determining anticipated required stress levels and by evaluating the results of all of these efforts toward establishing the feasibility of the idea. Since the surface bonding cement appears to have excellent possibilities,an outline for Phase II was developed. The use of surface bonding cement to accomplish seismic hardening of existing unreinforced masonry walls is a potentially economical solution to a problem that at present only has expensive solutions.
