This paper introduces the experimental program implemented to study the load-carrying capacity of seven reinforced concrete beam-column assemblages under monotonic vertical load against progressive collapse due to removal of the interior column. The specimens were designed and detailed according to the Egyptian code provisions. The specimens were one-quarter of the full scale and designed with and without seismic detailing to verify the effect of reinforcement detailing and flanges on the assemblage structural behavior. Each specimen represented a twoconsecutive beam spans subsequent to the elimination of the first story interior column. In all assemblages, the external two columns were restrained against the vertical and the horizontal deformations and loads were applied monotonically at the top of the interior column stub. For each load step, the results of mid-span deflection, concrete strains, reinforcing steel strains, and load capacities were documented. The tests showed that the compressive arch action (CAA) improve the beam-column assemblage flexural capacity. The arching capacity was noticed to be a function of the longitudinal reinforcement ratios, seismic and non-seismic detailing, and the

Regarding the failures due to corrosion, concern about corrosion damage has been intensified and some tests have been carried out in order to study the effect of corrosion on capability of bending and shear capacity of reinforced concrete beams. For as much as these studies is experimental commonly and using from its results subject to spend time and financial costs, this study is set to analyze behavior of corrosion found reinforced beams, using ABAQUS computer software. For this purpose, the sound reinforced concrete beams is modeled, first and simulating accuracy is confirmed by existing experiment results. Then corrosion found beams with different degrees are modeled by ABAQUS software and their results were compared with experimental results and finally, P-∆ charts are produced and provided for software models. In the way of simulations, effects of corrosion site, amount and intensity of corrosion, concrete compressive strength and bar yielding stress on behavior of reinforced concrete beams under corrosion is examined. In this investigation, the effect of different locations and different corrosion degrees is considered regarding changes which take place in cross section of steel, mechanical characteristics concrete and steel and integrity between steel and concrete.

Large scale MR dampers have been fabricated and several full-scale structures have been utilized semi-active devices to reduce the undesirable vibration responses [6][7][8].…”

An adaptive fuzzy-logic -controller (FLC) is proposed to actuate MR damper smartly. Minimizing the excessive responses of building should be considered as a multi-objective optimization problem. The new generation structural systems should be designed based on seismic performance level. Designing based on performance requires dynamic, heavy and repetitive time history analyses. The endurance time analysis method (ETA) is a modern dynamic method based on the performance of the structure, which leads to the reduction of time and number of structural analyses. To investigate the efficiency of Dolphin Echolocation-Fuzzy Logic Controller (DE-FLC) and ETA, several ET simulations were performed. The seismic responses of 11th-story benchmark building equipped with MR dampers were investigated in two cases of seven time-history analysis and six generation of ET functions. By using Dolphin echolocation, the optimal arrangement and the number of sensors and dampers is determined. The proposed DE-FLC controller demonstrates its efficiency by reducing the excessive displacement under seismic excitations in comparison with uncontrolled case and classical FLC. Furthermore, the results demonstrate that sixth generation of ETA can simulate responses of several time-history analyzes well with proper accuracy, without necessitating any several computational burden.
