Precast Chemically Prestressed Concrete Frame
The report describes in detail the fabrication and experimental studies of two prestressed concrete frame models. The fabrication of the models was carried out in order to investigate the feasibility of constructing concrete frames by connecting simple precast chemically prestressed structural elements. All elements had a 2.7/8 by 4-inch rectangular cross section and a nominal length of about 40 inches. Total percentage of reinforcement was 1.74. The structural elements were all self stressed by chemical prestressing through the use of an expansive cement developed recently at the University of California, Berkeley. History of expansion and the corresponding stresses developed during the curing process of these elements are presented. To assure continuity at the knees of the frames, the connections between the precast prestressed elements were developed by the use of special end-bearing plates and high-strength steel bolts. The experimental work consisted of a series of tests programmed to study the mechanical behavior of the simple structural elements and of the frames under proportional loading. (Author)
