Abstract: This investigation was undertaken to observe the strength and behavior of a one‐half scale, nine panel, flat plate with a banded arrangement of unbonded tendons. The test slab had three 10‐ft spans in each direction and ...

Abstract: This paper reports an experimental program conducted to measure the transfer lengths (or transmission lengths) of pretensioned seven-wire strands in pretensioned concrete specimens. The primary goals of the research were ...

Abstract: The purpose of this study is to investigate the behavior of prestressed concrete members containing unbonded tendons. First, a time-dependent nonlinear constitutive law for concrete was proposed in such a way that a solution ...

Abstract: In a companion paper, the program time-dependent analysis for prestressed concrete structures (TAPS) was developed for the analysis of prestressed concrete members with unbonded tendons. In this paper the inelastic behavior ...

Abstract: A load test of a prestressed concrete, one‐half scale model, flat plate with unbonded tendons is reported. The four panel model was 20 ft (6.1 m) square, 2.75 in. (70 mm) thick, with 8 in. (200 mm) or 7 in. (175 mm) square ...
