Re.: Mr Nevatia's dilemma --------------------
Ill-conditioned equations, which occur frequently in real life, can be solved only by so-called 'exact' or rigorous methods such as matrix inversion and not by iterative methods. Even in matrix inversion, it becomes necessary to use double precision. Our computer programs noramally work in single precision, that is, up to 8 significant places. If double precision is declared for the variables involved,then the calculations extend up to 16 significant places, precluding round-off errors so common in ill-conditioned equations.
I thought that increase in the stiffnes of the horizontal diaphragms, the slabs, will enhance diaphragm action and help to transfer lateral forces to the stiffer elements in the building, such as the shear walls or the braced frames.
