Maximum spacing of shear links = 0.75d = 0.75 × 211 = 158.75 mmĪ142 BRC Mesh can be provided or H8 250mm c/cįor more information on design and consultancy to accomplish the most challenging design brief, contact the author on Thank you, and God bless you. building with ribbed slab and grid slab International journal of Recent technology. Ribbed slab etabs how to#Any idea of approximations or tips of how to build the model. developed and evaluated by static analysis by ETABS. new model, waffle or Edit add to model) will probably do nothing good. The structure is very irregular and using the template for waffles slabs (i.e. I need to model a structure with waffle slabs. But for this design, we will therefore provide minimum shear reinforcement.Ī sw / S = ρ w,min × b w × sinα (α = 90° for vertical links) slab using etabs tutorial One way Ribbed RCC slab is a simply simply supported slab in most cases One-way ribbed slab design and detailing using autocad. Since Actual L/d (23.696) V Ed (17.25 kN), no shear reinforcement is required.Īccording to clause 6.2.1(4), minimum shear reinforcements may be omitted in ribbed slabs where transverse distribution of loads is possible. Ħ.7 m, 6.l m 6.7 m Ad Got 5.5 m, 6.2m է -5m 6.2m՝ 5.Therefore multiply basic length/effective depth ratio by 0.8 In comparison to the solid slab, the span limits of ribbed slabs are. The name of an existing ribbed slab property. And this is possible only in monolithically cast concrete which is the two-way grid of beams. described earlier (or to the flanged beam if the slab is ribbed). RIBBED SLABS to BS 8110:2005 (Analysis & Design) A Ribbed Slab gives considerable extra strength in one direction while a waffle slab gives added strength in both directions. Check the spacings between steel bars. Veja grtis o arquivo ETABS PT Slab Design enviado para a disciplina de Engenharia.Check always the reinforcement with the minimum and maximum limits.Design the beam and show the longitudinal steel, shear reinforcement, and rebar percentage. Conduct the checks to validate your model. Design the beam and show the longitudinal steel, shear reinforcement, and rebar percentage.Provide clear pictures of general steps of modeling the structure.Estimate the beams dimensions and assume the columns dimension is 30*55 cm.III 0 Design the following one-way ribbed slab by constructing a 3-D model utilizing ETABs and using the following data: Live load = 4 kN/m2 Superimposed dead load - 3.5 kN/m2 f'c = 24 MPa fy=420MPa In your report show the followings: Transcribed image text: 22:55 OS: 57% Read Only - You can't save changes to this file.
