Since the slab is a beneﬁt for the shear wall to stand against the out of plane deformation, the effect of the slab is neglected in the present investigation. The concrete shear wall is reinforced by steel bars in both horizontal and vertical directions. The Young’s modulus and Poisson’s ratio of the concrete and the reinforcing bars are de-. The present experimental work investigates the applicability and performance of a new strengthening method for concrete slabs, intended to increase their punching resistance using combination layers of steel wire mesh with epoxy attached to the concrete slabs’ tension face. Six simply supported square reinforced concrete slab specimens were tested up to failure under a central concentrated load.
English: The assessment of safety in existing bridges and viaducts led the Ministry of Public Works of the Netherlands to finance a specific campaing aimed at the study of the response of the elements of these infrastructures. Therefore, this activity is focused on the investigation of the behaviour of reinforced concrete slabs under concentrated loads, adopting finite element modeling and.

Bridges with reinforced concrete deck slabs are more vulnerable to environmental-induced deterioration mainly due to corrosion. Carbon and glass fiber reinforced polymer (FRP) bars are getting attention as an alternative to steel bars to enhance the overall performance of the concrete bridge deck slabs and minimize corrosion-induced deteriorations.
James G MacGregor's book "Reinforced Concrete" contains a section on Yield Line Theory for slabs. One part of the section addresses analysis and design for concentrated loads. I have used it from time to time for heavy concentrated loads in industrial facilities. Good luck.
Limit Design of Slabs for Concentrated Loads. Yield Line Theory is used to derive expressions for the flexural limit loads of reinforced concrete slabs subjected to simultaneously acting concentrated and distributed loads. The concentrated loads are assumed to have a rectangular footprint of any reasonable size and aspect ratio.
The slab reinforcement can be orthotropic, different over each Cited by: 5. Concentrated load tests on three one-way reinforced concrete slabs are described. The experimentally measured bar forces are compared with the predicted response Cited by: 6.
In addition to the slab tests published by Reißen and Rombach an extensive series of tests with 14 full scale cantilevered slabs without shear reinforcement (see Fig. 2, a/b/h/d = /// m, ρ l = %) has been conducted at the Institute of Structral Concrete at the Hamburg University of Technology (TUHH).
The test specimens were loaded with one or two concentrated loads (load Author: Lukas Henze, Günter Axel Rombach, Maike Harter. Abstract. The simplest routine structural element for illustration of design The response of reinforced concrete slabs to concentrated loading book in the Code is the one-way slab.
A one-way slab is defined for purposes of this book as a flexural member with depth small relative to other dimensions, supporting (gravity) loads applied normal to and directly over its surface, spanning in one direction between parallel supports, and reinforced for flexure.
Design of Reinforced Concrete Slabs B = x 1 where x = distance of load-from support closest to load I = effective span.
For slabs spanning in both directions published tables and charts should be used to find bending moment and shear per unit width of slab. A finite element model may be created to analyse a complicated loading arrangement. To describe the behaviour of reinforced concrete slabs subjected to concentrated loads close to the support, a new model is proposed.
This model is a combination of load-bearing quadrants and strips, and is based on the Bond Model [8, 9]. Online Concrete Slab on Grade Analysis Calculator For Slab Subjected to Interior Concentrated Post or Wheel Loading Assuming Slab is Reinforced for Shrinkage and Temperature Only.
Calculators for structural engineers, construction professionals and steel building specifiers. Concrete slabs on grade are a very common type of concrete construction. Floor slabs can range from a simple residential basement slab to a heavy-duty industrial floor.
However, no matter how basic or complex the floor is, the construction method is similar and includes; preparing the sub-grade and sub-base, placing the reinforcement and.
The “Slab on Grade” worksheet assumes a structurally unreinforced slab, ACI″Type B”, reinforced only for shrinkage and interior load condition is assumed for flexural is, the concentrated post or wheel load is assumed to be well away from a “free” slab edge or original theory and equations.
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 slabs were loaded to failure stage and the structural response of each slab specimens have been predicted in terms of deflection, variation of strain in concrete and steel, collapse loads and.
The equation of negative yield line for orthotropic reinforced concrete slab under concentrated load is found to be a symmetric and closed curve with determinate shape but indeterminate radius.
The ultimate bearing capacity is dominated by bending or punching shear of slab, depending on the depth and the reinforcement ratio of the slab.
Shear in reinforced concrete slabs under concentrated loads close to supports 20 Slabs vs. beams (1) • Transverse load redistribution • Geometry governing in slabs • Location of load • result of different load-carrying paths • Mid support vs end support • influence of transverse moment • Wheel size • more 3D action.
This study is aimed to investigate the potential benefits of embedding geogrids in concrete slabs-on-grade. In addition to four-point bending tests on unreinforced and reinforced concrete beams, large slabs-on-grade were built on top of local soils and aggregate inside a testing box and tested under monotonic static loads.
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 elongate.
A concrete slab is a common structural element of modern buildings, consisting of a flat, horizontal surface made of cast concrete. Steel-reinforced slabs, typically between and mm thick, are most often used to construct floors and ceilings, while thinner mud slabs may be used for exterior paving (see below).In many domestic and industrial buildings, a thick concrete slab supported on.
The slabs were loaded under two point static load up to failure and the structural response of each slab specimen was investigated in terms of the onset of cracking, deflection, ultimate load and.

R —Introduction. In the United Kingdom the design of reinforced concrete is based largely on the British Standards and BS Codes of Practice, principally those for 'Loading' (CP3: Chapter V: Part 2 and BS Part 1), 'Structural use of concrete' (BS81IO: Parts 1, 2 and 3), 'The structural use of concrete' (CP1 Parts 1, 2 and 3), 'The structural use of.j.
