Abstract: This paper proposes two procedures for designing a vortex drop shaft, both of which are based on a recently set up mathematical model. This model is different from previous ones as it considers the possible existence of negative pressure at the drop shaft inlet, thus allowing the incongruence of the previous models to be overcome. This paper presents an analysis of the reliability of the model, within which the calculation parameters have been tested using experimental data from a number of working drop shafts.

Abstract: Deflection computations for reinforced concrete beams form an important part in the design procedure of reinforced concrete structures. This study is divided into two parts; the first part studies the sensitivity of models to the experimental loaddeflection from previous work, and the second part studies the effect of vertical eccentricity according to the supports position on beam deflection behavior. The analysis is performed using a threedimensional model to determine the deflections in beams. A finite element analysis program is used considering nonlinear material behavior. The finite element model is chosen to conduct a parametric study in order to investigate the effect of vertical eccentricity according to the supports position on beam behavior. The study indicates that values of deflection depend on the position of supports (at below the beam or at neutral axis of the beam).
