Abstract: A. KMITA The purpose of this work is to present some aspects and main problems of theory and computations of RC (reinforced concrete) bridge slabs. The differential equation of the cracked bridge slab, using the classical variational method is worked out. The equation of bridge slab deflection with the boundary conditions and compatibility conditions in the crack are obtained. The total differential equations in the class of the general functions are shown. In this model the effect of discontinuity of the first derivative of deflection functions is taken. The numerical results of an approximate method of solutions of RC cracked plates with boundary element method (BEM) are shown.

Abstract: Structural design of tall buildings is generally governed by lateral stiffness. Outrigger structural systems, which produce lateral stiffness very effectively, are one of the most prevalently used structural systems for today’s tall buildings. With abundant emergence of complex-shaped tall buildings, when the system is employed for twisted or freeform tall buildings, its lateral stiffness is typically reduced compared with the cases when they are used for prismatic tall buildings. However, when the system is employed for tilted tall buildings, its lateral stiffness is increased. This paper studies lateral performance of outrigger structures employed for tilted tall buildings. Parametric structural models are generated using appropriate computer programs for this study, and the models are exported to structural engineering software for design and analyses of tilted outrigger structures of various tilted angles.
