Original scientific paper RC frame structures with specially shaped columns and RC frame structures with rectangular columns are different types of structures with different column sections. A progressive collapse analysis model of RC frames was proposed using the beam-column element and joint element based on the program OpenSees. Progressive collapse performance of the experimental frame was ...

The paper presents the results of a comprehensive study on evaluation effectiveness retrofit strategy existing steel buildings against progressive collapse. In this respect, it investigates performance and design solution to increase robustness Moment Resisting Frame buildings. A truss system added at building's rooftop level (i.e., ‘roof-truss’), intended define an alternative load path, was i...

in this paper a comprehensive approach is presented to improve power swings damping based on direct lyapunov method. the approach combines superconducting magnetic energy storage (smes) system with static synchronous compensator (statcom). considering the energy absorption/injection ability of smes, in transient states the combination exchanges both active and reactive powers with power system....

The present work is aimed at assessing the impact of strong column-weak beam (SCWB) criterion on seismic performance of optimally designed steel moment frames. To this end, different SCWB ratios are considered for steel special moment resisting frame (SMRF) structures and performance-based design optimization process is implemented with the aid of an efficient metaheuristic. The seismic collaps...

In this paper, an adaptable and architecturally flexible lateral stiffening system for tall timber buildings between 50 147 m is developed investigated. The based on a tube-in-tube concept. internal tube consists of braced core, the external frame structure with semi-rigid beam-column joints in façade. Based finite element framework, more than 500 000 simulations different configurations are ca...

ShareCam is a robotic pan, tilt, and zoom streaming video camera controlled by simultaneous frame requests from remote users. Robotic webcameras are commercially available but currently restrict control to only one user at a time. ShareCam introduces a new interface that allows simultaneous control by many users. We will demonstrate the implemented system using a Java-based interface at the con...

According to current design practices of steel moment-resisting frames, formation plastic hinges is unavoidable when the frames are supported by conventional column base systems, i.e., exposed-type and embedded-type due unequalized flexural moment demand on top first story columns [1]. Kimura et.al [3] has proposed mid-story pin system avoid from yielding realize beam-yielding mechanism applyin...
