Find the effective span which is lesser of (i) distance between centres of bearings, and (ii) clear span and effective depth. Slab design is comparatively easy when compared with the design of other elements. Slab systems can be continuously supported on walls, but beam systems usually need thickened piers under the beams. 100 klf DCOverhang = WC tOH * 1 ft. In case of calculation simulations the modelling is based on the approach. 113 klf DCBarrier = 0. the trail depth can be obtained using: Effective depth d= Span / ( (L/d) Basic x modification factor). Cantilever slabs are a typical one way slabs. Because of this rotation of footing can be avoided. The design procedure must include load calculations on the slab (ps) for both Case I and Case II. The number of Auto Design Cuts are defined when you draw the Support Line and can be modified in the Slab Design Strip spreadsheet. A grillage of beams within the concrete slab provides a stiffer and stronger final product than a conventional. Information on other aspects, su ch as materials, construction methods, placement of concrete, and finishing techniques, is. Just remember to add some extra concrete to your total order because running short is not an option. The punching problem of reinforced concrete flat slabs and flat foundations has two main aspects, related to load carrying capacity of these structures under shear forces. Flab Slab Analysis and Design is a lightweight application especially designed for building constructors that helps them design beamless concrete slab floors in accordance with ACI 318 frame method. d 2 Critical section for shear Concrete in this area is neglected for calculation 90° Fig. We will most likely have extra concrete on our volumetric mobile mixer. In two way slab, the ratio of longer span (to shorter span is less than 2. 5 it behaves as one-way slab. The two classifications are one-way slab and two-way slab. For Waffle Pod accessories 1. Design strip widths can be determined automatically by SAFE, or they can be manually defined by the user for more complex designs. These under all of the steel support legs and props. It assumes that the area under the slab as well as the slab edge are insulated to a minimum of R 10 (RSI 1. 1 INTRODUCTION 2. To use the Block Wall Calculator, simply enter the.

Design Criteria for Composite Steel Deck- same as non-composite • Allowable stress • Calculated theoretical deflection shall be based on the load of the concrete as determined by the design slab thickness and the load from the steel deck, uniformly applied on all the spans and shall be limited to L/180 or ¾ inch, whichever is smaller. This section, taken largely from the 1993 AASHTO Guide, briefly discusses the design process for JRCP and CRCP. slabs using computer simulations reflecting real behaviour. The design follows the PTI (IBC, UBC) recommendations, with enhancements where necessary (E-PTI). Default is 50 psf which you can change. SLABS is a program that can be used by structural engineers to perform a static analysis and design of reinforced concrete slab systems of any shape, including suspended slabs and slabs-on-ground. Slab Reinforcement. The bars we use in the Tension zone of the slab is called Bent. d 2 Critical section for shear Concrete in this area is neglected for calculation 90° Fig. 113 klf DCBarrier = 0.
