“…These charts have been found to produce a realistic estimation of short-term deflection similar to finite element analysis as well as experimental results [12]. Two closed-form expressions were obtained which describe the relation between the bending moments and all factors that affect it (the span ratio, the dimensions ratio of the loaded area and the ratio between the short span to the parallel length of the loaded area) [13]. to investigate how fibers affect structural behavior such as the possibility for redistribution, crack patterns, and load-carrying capacity.…”

The self-weight of the concrete slab in high-rise building construction significantly affects the risk of structural failure in earthquake-prone areas as the earthquake force is directly proportional to the mass of the building. To reduce the building mass then the sandwich concrete slab is introduced. This study focuses on variations of aspect ratio effect on the slab behavior under central point loading. The aspect ratios are set at 1.0, 1.26, 1.5, and 2.0. A normal concrete slab with an aspect ratio of 1 as the control specimen is prepared. Tension reinforcement of D10-150 is placed in both x-and y-direction. While the compression reinforcement of P8-200 for both directions is used. The slabs were supported on four edges and tested under a central point load. Results found that the slab with an aspect ratio of 2.0 has a greater stiffness than other slabs as well as the resistance load capacity. The slab with an aspect ratio less than 2.0 behaves similarly with no significant differences. Generally, the slab ductility index decreases with increasing the aspect ratio. All slabs have ductile behavior which is indicated by both the strain measurement and the relationship of the load-deflection curves. An aspect ratio of 2.0 as the limit used by the Standard for distinguishing one-way and two-way slab elements is proven valid and acceptable.

Structural analysis of reinforced concrete retaining walls is commonly performed on a two-dimensional model. This approach is suitable only when the applied loads are evenly distributed over the wall length. In cases of concentrated loads (e.g. vehicle impact), two-dimensional modelling brings highly distorted results in comparison to the more realistic three-dimensional modelling. This article presents a study on how wall height and load position affect the result distortion, comparing the outcomes of two-and three-dimensional modelling. The peak value of bending moment was chosen to be the parameter used for the comparison. The error due to the use of two-dimensional model for concentrated loads was quantified. The conclusion of the study is a proposal of correction coefficients that can be applied to the results of two-dimensional analysis, in order to acquire results of equal precision as these from three-dimensional analysis.
