What is Grade of Concrete .Read More about Mix Design of concrete for better Strength & Durability of your Reinforced Concrete Structures. https://youtu.be/VFrNWSWODl8 https://youtube.com/c/CivilStructuralTechGuruji What is Concrete: It's mixture of  Cement,Sand, Aggregate , admixture with normal water to give Comprehensive strength at specified 7or 8 days Test. What is Grade of Concrete:- The grade of concrete varies greatly in accordance with the changing proportion of its constituent materials. The proportion and the ratio, in which the materials should be mixed together to obtain a certain grade of the concrete, has already been specified by IS 456:2000. The above mixes given in the table are called Nominal Mix. In the era of industrial and infrastructural developments, to cater the need for high strength concrete and overall improvement of the concrete properties, various high strength concrete has been introduced, taking it way more than M100.

why Shear force & bending moment zero at free end in Portico slab /beam Practical understanding why Shear force & Bending moment zero at free end cantilever portico slab beam Dash link subscribe & bell icon to know more: , https://youtube.com/c/CivilStructuralTechGuruji #cstechguruji#subscribe#structuralanalysis civil Engineering #rccdesign, reinforcement, reinforced concrete portico design building construction I have explained following: A cantilever is  a beam supported only at one end, with load carried over the overhanging . This is in contrast to a simply-supported beam, which is supported at both ends. Cantilevers provide a clear space underneath the beam without any supporting columns or bracing. 1.what is SF at free end of the cantilever beam? 2.what is the shape of BMD with cantilever beam with load at whole span? 3.How do you draw SFD and BMD for cantilever beam? 4.How do you draw SFD  for cantileve...

EASIEST METHOD TO FIND SFD BMD FOR SIMPLY SUPPORTED BEAM WITH CENTRAL POINT LOAD

Image
  EASIEST METHOD TO FIND SFD BMD FOR SIMPLY SUPPORTED BEAM WITH CENTRAL POINT LOAD A t the ends of a simply supported beam the bending moments are zero. At the wall of a cantilever beam, the bending moment equals the moment reaction. At the free end, the bending moment is zero. Beams – SFD and BMD   • Draw the SFD and BMD.  Determine reactions at supports. • Cut beam at C and consider member AC, V = + P 2 M = + Px 2 • Cut beam at E and consider member EB, V = - P 2 M = + P ( L - x ) 2   • for a beam subjected to concentrated loads, shear is constant between loading points and moment varies linearly
