    What is the center of Stiffness?

    I added more information, Centre of stiffness is also called as a centre of rigidity. According to IS 1893-2002, it is the point from which the restoring force resultant of the system acts. In this case, the lateral forces pass from the centre of stiffness. Stiffness (K)= (force on the system (P) /Read more

    Well, if you're analyzing a beam, then the quickest and easiest way is hands down, the moment - area method.

    Well, if you’re analyzing a beam, then the quickest and easiest way is hands down, the moment – area method. Students often overlook it and delve into complex methods while the problem may be solved a lot easily.

    Other than this, there are often other quick methods depending on the question. For example sometimes the conjugate beam method is not such a bad choice. If you can write the moment curvature equation and are quick at differentiation, you can use that.

    I for one, never get into slope deflection method unless it is strictly needed. I stick to moment area, conjugate beam and the 4th order differential equation.

    Also, a friendly tip : just have a look at the options especially in the IES paper. They never push you into long calculations. You could sense that some options just have to be wrong and are nowhere close to be correct. In GATE, this approach doesn’t fare well though.

    Hope it helps.

    First of all you have to design that story building to provide reinforcement for all members such as slab ,beam,etc. by using different code such as IS etc.

    Bar bending schedule (BBS) is a comprehensive, detailed list of reinforcement bars to be used in an RCC construction along with their number, location, mark, type, size, lengths, details in correspondence with the drawings. It also includes the timing for the bending of each bar, and that is why it’s called a bending schedule.

    Bars are needed to be bent in order to give them the desired reinforcement shape. Stirrups and anchorages are two places where bar bending is compulsory. In addition, when we need to join bars, we might want to bend them on the ends before welding or fastening.

    BBS also gives a clear and logical understanding as to how much bars of what sizes will be needed to be procured and bent by what time so that no delay, all procurement is done with minimal transport expenses, and all bending is done with minimal machine and labor costs.

    But why you want a column raised on a slab. The moment you do, a point load will come on slab at that point so it is not possible/advisable. Describe problem for alternative solution.

    You can’t build a column on slab unless slab is designed for the load you needed for. It is regarded as pt load on slab which is usually not designed for it, it all relies on what purpose you want to raise the column on slab.
