EXPERIMENTAL STUDY OF REINFORCED CONCRETE SKEW HOLLOW CORE SLABS. ABSTRACT Reinforced concrete Hollow Core Slabs (HCS) are among the types of structures that are used in bridges for the last three decades.

They evolved a highly efficient and aesthetically pleasing for medium and long span bridges (i.e. span range of m). Keywords: reinforced concrete, review, voided slabs, experimental, theoretical. INTRODUCTION Voided slab systems are an alternative to conventional concrete slab construction.

Voided slab systems are lighter than solid concrete slabs while maintaining the ability to have large spans. Because of lessFile Size: 1MB. Use of voided slab is spreading all over the world in recent times.

Voided slab system has many advantages over conventional solid slab and some drawbacks also. There is a lot scope for studying the voided slabs in India.

The compatibility of these foreign techniques must be workout with Indian : Vikas P. Bhamare, Pradip D. Jadhao, Abhijit J. Pawar. All tests ended in web shear failure of slabs close to the supports of the beam. due to deflection of the supporting beams.

The voided slab is consisted of mm bottom and top slabs with diameter of circular voided equal mm and the distance center to center of these circles mm.

Download Code Voided Deck Slab Modelling using Grillage wizard. This paper presents a computer software which allows the generation of a complete structural model of a concrete bridge with a voided slab deck, a common design for medium span bridges.

The code implements the orthotropic plate paradigm and provides a graphical user interface, which allows both preprocessing and post-processing, linked to a commercial finite.

The types of bridges tested included two reinforced concrete open spandrel arches, two reinforced concrete filled spandrel arches, one reinforced concrete slab bridge, and one two span reinforced concrete stringer bridge. The testing of each bridge consisted of applying a static load at various locations on the bridges.

The bridge structure displayed cracks on the soffit of the deck slab and had been posted because of insufficient capacity of the slab. In order to remove the load limits of the structure, the bridge deck slab was strengthened with adhesively bonded CFRP composite strips and wide wet lay-up carbon fabric.

Full-scale testing and numerical analysis of a precast fibre reinforced self-compacting concrete slab pre-stressed with basalt fibre reinforced polymer bars Preliminary tests on the employed materials and a 3-point load test on the slab element are presented, together with indications on its manufacturing process.

Table 1 summarises the Cited by: 8. BASIC CONCEPTS OF BRIDGES Solid Slab Bridges are basically concrete in which internal stresses of a suitable magnitude and distribution are introduced so that the stresses resulting from external loads are counteracted to a desired degree. In reinforced concrete members, the pre-stress is commonly introduced by tensioning theAuthor: G.

Krishna, M. Kameswara Rao. The cross-section of a prestressed concrete voided slab bridge is shown in Figure 1.

The bridge spans 25 m, has a self-weight of kN/m is to carry a live load of 50kN/m. The initial design of prestressing is to provide 8 straight tendons with a constant eccentricity of mm which will prestress the concrete with a total compressive force.

A new window will appear. Fill in the fields as appropriate under the Description tab: Note: The description. Concrete is poured around these plastic forms to create internal voids in the slab. Voided biaxial slabs, sometimes called biaxial slabs, are a type of reinforced concrete slab which incorporates air-filled voids to reduce the volume of concrete required.

Voided slab systems were developed using segmented void formers such as spherical or oval plastic balls for two-way slab applications. This type of slab is expected to behave like a general two-way reinforced concrete slab because it has segmented voids, rather than the continuous voids of hollow core by: 7.

When the existing RC voided slab bridge is broadened, whether the new bridge could be constructed with PC voided slab structure or not, is a matter of interest and perplexity to designers. This paper presents the feasibility that whether these two types of voided slab bridges with different arrangement of bars could be spliced.

Bridge Load Test and Load Rating of Reinforced-Concrete Slab Bridges. The safe load capacity of a bridge structure is generally determined from bridge load-rating calculation.

Several methods, namely allowable stress method, load factor method, and load and resistance factor rating (LRFR) method, are currently used for this calculation.

The test results show that the shear strength decreases with increasing plastic hinge rotation. A description of the obtained results is exposed in [1] and [2].

The second part of the experimental program part consists of tests on large scale reinforced concrete bridge. A hollow core slab, also known as a voided slab, hollow core plank or simply a concrete plank is a precast slab of prestressed concrete typically used in the construction of floors in multi-story apartment slab has been especially popular in countries where the emphasis of home construction has been on precast concrete, including Northern Europe and former.

Reinforced-concrete bridges may have various systems: beam (with simply supported or continuous beams), frame, arch, or combined. Beam reinforced-concrete bridges are the most common type. Spans with plate structure are generally used to. Concrete is absolutely horrible in tension. When, not if a void (or water saturates the soil to the point of plasticity) develops beneath the crete the bottom 1/2 of the crete is now in tension, crete is lousy and failure prone in tension.
