Abstract

Prestressed concrete has long been accepted in statically loaded structures. Thus, for many years now we have seen the construction of prestresed concrete bridges, dams, pipelines, reservoirs and various structures including more recently atomic reactor pressure vessels. These stand as irrefutable proof of engineers’ confidence as to the integrity of this new material. In recent years prestressed concrete has been used in seismic resistant structures. Just like any other new material, it will attract criticism and comment, sometimes by people who may not have had the opportunity of full investigation of the material in question. Furthermore, today engineers are more critical of any new material or technique and will seldom accept them unless conclusive evidence of their performance can be produced. This is as it should be. The purpose of this paper is to observe the application of prestressed concrete to seismic …
