two-way joist concrete slab floor waffle slab system analysis and design design the concrete floor slab system shown below for an intermediate floor with partition weight of 50 psf, and unfactored live load of 100 psf. the lateral loads are independently resisted by shear walls. a flat plate system will be
reinforced concrete slab design and detailing guidelines for depth of slab, loads on slab, reinforcement guide for one-way and two-way slabs as per is 456:2000 have been tried to present here. the load on slab comprises of dead load, floor finish and live load. the loads are calculated per unit area
interior floor slabs are usually not subjected to the same severe temperature gradients experienced by outside pavements. therefore it is reasonable to design for the maximum temperature range that the slab will experience during its service life. however, even interior climate controlled spaces can experience temperature ranges of 40 o to 60 of.
designing of slabs depends upon whether it is a one-way or a two way slab, the end conditions and the loading. the third chapter presents the design calculations of slab and ding of
reinforced concrete effective span centre-to-centre distance between supports longer dimension of a rectangular panel of slab for yield line calculations modular ratio = es/ec design bending moment per unit width of slab modified to account for axial load moment per unit width about x-axis moment per unit width about y-axis
concrete floor slabs design requirements, equations and calculator : civil engineering design knowledge. floor slabs on grade should be analyzed for adequate structural live loads. since floor slabs maybe designed for moving and extreme live loads, the design should be checked for stationary live loading conditions as well.
these calculations shall govern the structural portion of the working dings. however, where any discrepancies occur between these calculations and the working dings, the engineer shall be notified immediately so proper action may be taken. the structural calculations included here are for the analysis and design of primary structural system.
basis of floor slab on grade design 2-1. stresses. thermal expansion and contraction of the concret e the structural design of a concrete floor slab on grade is primarily controlled by the stresses caused by moving live loads and in some cases the stationary loads. stresses in floor slabs on grade resulting from vehicular loads a re a function
sample design calculations. this appendix presents design examples of the retrofitting techniques for elevation, dry floodproofing, wet . measures, such as floor anchors or additional slab mass, or non-structural measures such as allowing the lower level to flood, are utilized to offset/equalize the buoyancy forces.

this video shows you how to calculate the amount of concrete required to pour a concrete slab on ground with splayed edge beam and a rebated edge. while the calculations are relatively simple its
perform calculations for the design of concrete floors on grade. reference: unified facility design criteria - concrete floor slabs on grade subjected to heavy loads floors - max. stationary ll: calculate the maximum stationary live load that concrete slab-on-grade floor can support.
by deflections. round slab thickness up to the nearest ¼. use a spreadsheet to design each section and show your results with a sketch elevation view . submit hand calculations matching the spreadsheet for one section. include units on all numbers. plan view of floor system f'c = 5000 psi
more detailed explanations and examples of reinforced concrete beam and slab design can be found in my text. note that the strength design method is used; moments must be computed based on factored loads. calculator works for rectangular beams, positive-moment and negative-moment t-beams, and 1-way slabs, as shown in the sections below:
floor loading calculations make better racking decisions. every warehouse floor has a limitation of maximum pounds per square foot. sadly, too often companies exceed that maximum floor loading, which causes warehouse floors to crumble.

openings in hollow-core slab floors occur often. the short slabs are supported by a trimmer that is supported by the adjacent continuing slabs fig. 1 . special calculations are not required if the opening has a size of one or two times the slab width. however, sometimes larger openings are needed, for example for large flight of stairs.

rcd:- one way slab design / design of a one way rc slab. in this tutorial 1st we will learn what is one way slab? then we will go ahead for design process . actually a one way slab satisfy the
the thickness of a floor slab must be determined early in design because the weight of the slab is an important part of the dead load of the structure. the minimum thickness can be determined by many factors: shear strength of beamless slabs usually a controlling factor ; slab must be thick enough to provide adequate shear strength
