WHAT IS ONE WAY SLAB AND HOW TO DESIGN ONE WAY SLAB WITH DESIGN EXAMPLE FOR A BUILDING PLAN ALSO WITH BAR BENDING SCHEDULE

WHAT IS ONE WAY SLAB

A slab is supported only one direction that is one way slab  now tha loads are transferred only this two supports .therefore the main reinforcements are provided perpendicular to supported direction.

Also the slab is supported four sides but the length breadth ( ly/lx)ration is greater than or equal to two , the slab is designed as one way slab. Therefore assumed the loads are transferred only one direction and designed that slab is one way slab.

WHAT IS DOUBLY REINFORCED BEAM AND HOW TO DESIGN DOUBLY REINFORCED BEAM WITH DESIGN EXAMPLE

WHAT IS DOUBLY REINFORCED BEAM
Concrete Have High Compression Strength And Very Low Tensile Strength For In This Reason Steel Reinforcement Is Provided For Tension Zone Because Steel Reinforcement Have High Tensile Strength.

For Single Reinforced Beam Reinforcement Is Provided Only Tension Zone Only (Bottom Side Of Beam) Other Case Both Tension And Compression Zone Of Beam Is Provided Reinforcement (Top And Bottom Of Beam ) That Is Called Doubly Reinforced Beam.

For Singly Reinforced Beam Minimum Two Numbers Of Bares Provided In Compression zone But It Does Not Consider For Moment Of Resistance Calculation .When We Consider This Reinforced Steel Bas Are Calculation Of Moment Of Resistance At The Time We Have To Provide Additional Tension Steel In Tension Zone Therefore To Reduced The Over Reinforced Section.

For Design Of Doubly Reinforced Beam First Find Out Limiting Moment Of Resistance And Area Of Tension Steel ( Ast ) In Singly Reinforced Section Then To Find Area Of Compression Steel (Asc) And Area Of Addition Tension Steel (Ast) To Resistance The Excess Bending Moment (Mu2)
