Service load tests of a post-tensioned flat slab with unbonded tendons. Experimental results and comparison with analytical predictions

Abstract

In this paper, which is the continuation of one piblished in ""Hormigón y Acero"", nº 177, the results of part of the tests of a large scale model of a post-tensioned flat slab are presented. Only the results of service load testsare reported herein, while the results of the failure test will be descirbed in a future paper. The obtained reactions, deflections, strains and stresses, internal moments, and distribution of forces are presented and compared with analytical predictions. Conclusions relative to the structural behavior and design criteria of this kind of structures are drawn.
