Early striking and improved backpropping for efficient flat slab construction introduction the european concrete building project is a joint initiative aimed at improving the performance of the concrete frame industry. Design of flat slabs and given their guidelines in their respective codes the aim of this project is to try and illustrate the methods used for flat slab design using aci-318, nz- 3101, and eurocode2 and is: 456 design codes.
Seismic vulnerability of flat-slab structures 31 overview of design and analysis considerations in flat-slab there are several approaches to construct . Existing approaches to design flat slabs on non-rectangular column layout are briefly reviewed methods involving trial and error, like yield line design (considering the slab with an assumed steel distribution and assessing the load capacity for possible yield line patterns) or elastic finite element. Examine each design approaches used to design for flexure in flat slab such as yield line analysis, hillerborg’s strip method, the simplified coefficient method for bs8110 or eurocode 2 and direct design method for aci. Structural performance of rc flat slabs connected to steel columns and design approaches do not the practical design of hybrid flat slab-to-steel column .
