Time-dependent behaviour and design of composite steel-concrete structures

Abstract

Steel-concrete composite structures are widely used throughout the world for buildings and bridges. A distinguishing feature of this form of construction is the combination of concrete and steel\ncomponents to achieve enhanced structural performance.\nThe time-dependent response of concrete and its infl uence on the service behaviour and design of composite structures are the main focus of this SED. For the fi rst time, a publication combines\na state-of-the-art review of the research with the available design specifi cations of Europe, Australia and New Zealand, and USA. This publication intends to enhance the awareness of the\nservice response of composite structures and of the latest research\nand standards’ developments. It is aimed at designers and\nresearchers alike.\nThe review of research available in open literature is provided and\narranged according to structural typologies, i. e. slabs, beams, and\ncolumns. It serves as background information for current service\ndesign rules and provides insight into the most recent research\nadvancements. The review of available design guidelines presents\nthe similarities and differences of the recommended service\ndesign procedures infl uenced by concrete time effects. Selected\ncase studies of building and bridge projects show possible design\napproaches and the rationale required when dealing with the\ntime-dependent response and design of composite structures.\nThe authors of this publication are design engineers and academics\ninvolved in the service design and research on the time-dependent\nresponse of composite structures.
