To control structures against wind and earthquake excitations, Adaptive Neuro Fuzzy Inference Systems and Neural Networks are combined in this study. The control scheme consists of an ANFIS inverse model of the structure to assess the control force. Considering existing ANFIS controllers, which require a second controller to generate training data, the authors’ approach does not need anot...

In this paper, a procedure has been presented to develop fragility curves of structures equipped with optimal variable damping or stiffness semi-active tuned mass dampers (SATMDs). To determine proper variable damping or stiffness of semi-active devices in each time step, instantaneous optimal control algorithm with clipped control concept has been used. Optimal SATMDs have been designed based ...

The isolation technique is widely studied and applied in structural engineering due to its excellent seismic performance. However, the existing research mostly focuses on conventional structure under action of regular ground motions. In this paper, a story-adding structure, base-isolated isolated were simulated by using numerical simulation methods. dynamic response characteristics three struct...

The Incremental Dynamic Analysis (IDA) represents a promising design approach to assess the performance and post-earthquake load carrying capacity of steel frames. Generally, only maximum transient inter-story drift is considered as damage intensity measure (DM), when IDA carried out. In Authors' opinion, better appraise all aspects characterizing state structures, additional DMs should be cons...

Construction of building omitting an infill wall mostly in ground floor and other floors has led a to face soft story failure mechanism. This omission is for commercial purposes parking vehicles floor. In this study, study on the behavior structure done when happens different levels. A explained as per NBC 201 205 taken into consideration. Soft assigned all responses separately. An equivalent d...

Abstract Earthquake is one of the horrible natural disasters. With considerable developments in constructional science, experts have been able to find out factor forces that cause earthquakes damage and destructions different types buildings, including residential commercial caused by earthquake are high importance need be considered. The multi-story buildings usually weak points building, whic...
