| Abstract: | A mixed method is used to calculate the internal forces of the crossed beam system grids and open-web grids.It applies to analysis of the internal forces for the two-way rectangular grid,two- way diagonal grid,three-way grid and the open-web grid structure in any boundary condition.It is simple and easy in working out the solution for all kinds of grids.This paper also presents the moment- dividing coefficients of beams with regard to the shearing displacement, the rod-end moments and the shears of some elementary beams having nod displacement or bearing loads for consulting in calculating. |
