Abstract:
A series-of studies at Materials Testing Laboratory Purdue University, which evaluate several of the possil bilities concerning the use of precast beams or joists for small house construction. Three typical precast ioists (3 in. x 8 in. x I2 ft long) were studied as follows: A prestressed Haydite concrete joist, a conventional Haydlte joist, and a prestressed segmental joist. Com- parative test values were determined for both con- ventlonally-reinforced and prestressed units and are presented in graphical form. The results include a theoretical analysis of each joist in comparison with the stress measurements in the tests.
