RCC Structures Design If K is a constant depending upon the ratio of the width of the slab to its effective span l, x is the distance of the concentrated load from the nearer support, bw is the width of the area of contact of the concentrated load measured parallel to the supported edge, the effective width of the slab be is Kx (1 + x/l) + bw K/x (1 + x/d) + bw Kx (1 - x/l) + bw All listed here Kx (1 + x/l) + bw K/x (1 + x/d) + bw Kx (1 - x/l) + bw All listed here ANSWER DOWNLOAD EXAMIANS APP
