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 design. A concrete slab is a common structural element of modern buildings, consisting of a flat, horizontal surface made of cast concrete. The test articles were reinforced concrete slabs mounted on a reaction structure for testing. The design of the simply supported slabs revealed that, it is possible to replace ordinary reinforcement with steel fibres but requires large fibre fractions, as those used in this project were not enough. 4. Deflections and shear stresses may also be controlled by adding beams instead of column capitals. For the slab tests, the imposed energy on a slab was compared with the minimum energy causing the slab to scab, which was predicted using empirical formulae. The direct study of measurements, performed on a 1/3-scale model, serves to understand the primary mechanical phenomena involved during impact phases. Results that are obtained from RC plate experiments in literature under impact loads are found to © 2008-2021 ResearchGate GmbH. The Iraqi Journal For Mechanical And Material Engineering. Large live loads and small limits on permissible deflections may force the use of large column capitals. A concrete slab is a common structural element of modern buildings, consisting of a flat, horizontal surface made of cast concrete. A reinforced concrete slab is a key structural component and is used in houses to provide flat surfaces (floors and ceilings). Concrete Structures . For slabs spanning in both directions published tables and charts should be used to find bending moment and shear per unit width of slab. Concrete slabs are effective systems where putting columns interrupts the structure's (Audiences, parking lots, hotels, airports, etc.) Slab supported on two sides and bending takes place predominantly in one direction only is called One Way Slab. A complex drop-mass apparatus is used to conduct experiments and investigations on the impact dynamic behavior of RC slabs The focus was on the response stage of the linear elastic field and how to correlate this re-sponse stage to the drop-height depending on raw experimental data. displacements, energy absorption capacities and damage patterns are changed due to support conditions and Significant damage also occurred in the test with the high seismic velocity backfill.
