Abstract:
Included in this publication are reports on temperature-induced deflections and observed deflections of reinforced concrete slab systems; measured and long-term deformations; deflection analysis of cable-stayed segmental prestressed concrete bridges; lateral stiffness characteristics of reinforced concrete frame-wall structures; rational deformation prediction of prestressed members; a study of service load deflections and ultimate load deflections of flat slab structures; probabilistic approach to deflection controlled reinforced concrete slab design; deformations and stresses in flanged concrete structures due to temperature differentials; structural serviceability under dynamic loading; and deflections of: partially prestressed members, waffle slabs, concrete slabs under construction loading, and cracked prestressed concrete members.

This report summarizes available methods for calcu-lating deflections of reinforced concrete beams subjected to temperature change. Selection of design temperatures and temper-ature gradients is discussed as well as the effects of cracking on response in the service load range.

This report is in two distinct parts. Part I is a summary of published studies on slab deflections (3 from Australia, 1 from Scotland, 1 from Sweden, 2 from U.S.). The summary focuses on construction practices and materials quality. Comparison of deflections calculated by various methods with actual long-term deflections is made in some cases. Part II summarizes several construction problems and mate-rial deficiencies which can contribute to large long-term deflec-tions. Focusing on large construction loads, the authors show

A 120m tall building incorporating both in-situ and precast post-tensioned concrete components was instrumented to observe some aspects of its structural behaviour. The instrumentation was commenced more than ten years ago, it includes embedded and surface strain and temperature transducers, survey reference points, wind pressure tappings, and anemometers above the roof of the building to measure wind characteristics. The paper describes the strain and deformation instrumentation and method of data acquisition. The measured long-term vertical strains and deformations in one of the columns are presented and are compared with values predicted by two methods which are suitable for use by designers. Reference is made to the results of an extensive materials testing programme the results of which enabled the assessment of methods of prediction for the long-term creep and shrinkage properties of the concrete.

This paper discusses camber control in segmental precast prestressed concrete cable stayed bridges. The prototype bridge structure consisting of three continuous spans is analyzed both during erection and service stages. The method of predicting the initial camber during erection and calculation of the required pre-tensioning forces in the cable stays to produce this camber are discussed. A numerical example analysing deflections for a typical segmental prestressed concrete bridge is presented.
