Arching Action in Reinforced Concrete Beams. 22nd Australasian Conference on the Mechanics of Structures and Materials, AC Sydney, NSW, Australia, December , FarhangVesali*, N., Valipour, H. and Samali, B. (). Numerical Challenging of Capturing Membrane Action in Reinforced Concrete Beams and One-Way Slabs. 6th. A general discussion of slab analysis and design is included, followed by an exploration of key methods and theories. Following chapters discuss other important issues, including shear strength, serviceability, membrane action, and fire resistance.
This paper outlines basalt and carbon fibre reinforced polymer (BFRP and CFRP) strengthening of laterally restrained concrete floor slabs. In-plane restraint has previously been shown to enhance slab capacity due to the development of internal compressive membrane action (CMA), which is generally neglected in codified strength assessments. This e-learning session will explain what arching and membrane action are, how it will influence the behaviour of your reinforced concrete structure, and how to cope with this in your reinforced.
A numerical example, in which a rectangular reinforced concrete slab is modeled at elevated temperatures, is presented. The influences of different thermal expansion characteristics, tensile membrane action, and differential temperature distributions across the thickness of the slab . In this paper, the development of compressive membrane action in a reinforced concrete slab is analysed using the finite element software SAFIR . The modelling approach consists in representing a 1 m wide strip of the slab, modelled with shell elements positioned on .

The American Concrete Institute. Founded in and headquartered in Farmington Hills, Michigan, USA, the American Concrete Institute is a leading authority and resource worldwide for the development, dissemination, and adoption of its consensus-based standards, technical resources, educational programs, and proven expertise for individuals and organizations involved in concrete design Cited by: (PDF) Membrane action in lateral restraint reinforced concrete slabs | Gang Wang - Abstract Based on the assumption of additional three-hinge arching action, an analytical method was proposed to predict the additional load of lateral restraint reinforced concrete (RC) slab under compressive membrane action (CMA), and its ultimate.
The formation and influence of compressive membrane action in reinforced concrete slabs is discussed. An experimental program is described, in which two large-scale slab specimens were tested under concentrated midspan loads.
One slab was restrained against lateral expansion at the ends, while the other was free to by: Compressive membrane action in reinforced concrete one-way slabs. In T. Tan (Ed.), EASEC-8 - the Eighth East Asia-Pacific Conference on Structural Engineering and Construction (pp.
1 - 6). Singapore: School of Civil and Environmental Engineering, Nanyang Technological University, by: 3. Abstract The behaviour of reinforced concrete one-way slabs subjected to horizontal translational end restraint is described in this paper.
The presence of the end restraint induces compressive membrane action in the slab, increasing its strength and stiffness above that calculated using ßexural by: 5. Bending and membrane action in concrete slabs. Martin Gillie the response of steel‐concrete composite structures in fire conditions is largely governed by the behaviour of the reinforced concrete floor slabs.
This paper obtains a detailed understanding of the strength of heated concrete floor slabs when subject to the combined bending and.
Analysis of the tests and numerical simulations reveals that this increase of fire performance is due to the development of tensile membrane action in the reinforced concrete slab.
This book will explain and illustrate how the development of tensile membrane action can occur in composite steel framed buildings. 6 Bridge Engineering Issue BE0 Analysis of compressive membrane action in concrete slabs Zheng et al.
The experimental models represented a full-scale concrete bridge deck slab strip. Compressive membrane action (CMA) occurs in reinforced concrete members if lateral expansion (dilatancy) is restrained; see Fig. Longitudinal expansion of reinforced concrete members can be prevented either by applying external normal or constraint forces, or by providing specific support conditions.
Localized tensile membrane action develops in the SWM-reinforced panels at large deflections caused by contact detonation. It is a self-equilibrating mechanism comprising a tensile net in the central region surrounded by a peripheral compressive ring of concrete.
PUNCHING FAILURE AND COMPRESSIVE MEMBRANE ACTION IN REINFORCED CONCRETE SLABS by GEORGE IVOR BARRY RANKIN, () Thesis submitted to The Queen’s University of Belfast for The Degree of Doctor of Philosophy I Faculty of Engineering Department of Civil Engineering October Arching or compressive membrane action in reinforced concrete slabs occurs as a result of the great difference between the tensile and compressive strength of concrete.
Cracking of the concrete causes a migration of the neutral axis which is accompanied by in-plane expansion of the slab at its boundaries.
If this natural tendency to expand is restrained, the development of arching action enhances the strength of the slab. The term arching action. It is assumed that the reinforcement acts as a plastic membrane.
On comparison with test results the theory is shown to be conservative. The load carried by tensile membrane action is found to be considerable and for heavily reinforced slabs it can exceed the ultimate flexural strength. Comprehensive, up-to-date coverage of reinforced concrete slabs-from leading authorities in the field.
Offering an essential background for a thorough understanding of building code requirements and design procedures for slabs, Reinforced Concrete Slabs, Second Edition provides a full treatment of today's approaches to reinforced concrete slab analysis and s: 2.
The only book devoted exclusively to reinforced concrete slabs, the second edition of this reference classic has been brought completely up to date. Not only does it contain basic information on the design and analysis of reinforced concrete, the new edition includes material on computer optimization, Equivalent Frame Method, and lateral load.
Title: Punching Shear Failure in Reinforced Concrete Slabs with Compressive Membrane Action Author(s): W. Salim and W.
Sebastian Publication: Structural Journal Volume: Issue: 4 Appears on pages(s): Keywords: failure; punching shear, reinforced concrete; slab. Date: 7/1/ Abstract: This paper presents the results of an experimental study of the ultimate punching load.
Arching and membrane action are clear examples of a nonlinear phenomenon that cannot be taken into account in a linear analysis. Therefore, a nonlinear analysis is strongly recommended in order to understand the behaviour and optimise the design of your slab in the most optimal way in terms of safety and cost.
Later chapters discuss other important issues, including shear strength, serviceability, membrane action, and fire resistance. Comprehensive and accessible, Reinforced Concrete Slabs, Second Edition appeals to a broad range of readers-from senior and graduate students in civil and architectural engineering to practicing structural engineers, architects, contractors, construction Reviews: 1.

The lateral stiffness and strength required of supporting beams and exterior panels of continuous reinforced concrete slab-and-beam floors in order to ensure membrane action in the panels at ultimate load is considered.
It is shown that tie reinforcement may be required in the supporting beams to carry the membrane forces. ASCE Subject Headings: Concrete slabs, Reinforced concrete, Structural behavior, Slabs, Temperature effects, Membranes, Composite materials, Floors Editorially Related Modeling Membrane Action of Concrete Slabs in Composite Buildings in Fire.Tensile membrane action in reinforced concrete slabs was a popular topic in the 's and 's.
However, the development of theories on this subject was limited, mainly due to the unforseen beneficial effects of tensile membrane action on the behaviour and design of buildings under fire conditions.Abstract.
