ABSTRACT
The literature does not pay any attention to stiffness of a horizontal connection of floor slabs between each other in a platform joint. The objective of this paper is to analyze the level of development of calculation methods for stiffness of joints of panel buildings, compare the analytical calculation and numerical solution. There have been analyzed formulae for calculation of compliance of platform joints of panels given in the regulations. There are given results of calculations using numerical methods for defining compliance of a platform joint and comparison with the analytical solution. As the result it is concluded that for the vertical direction the numerical solution is almost equal to the analytical one (the difference is less than 5%), at shear along the wall the discrepancy is a bit bigger, the largest discrepancy with the analytical solution occurs at shear across the wall.
