During the analysis of reinforced concrete structures, the infill wall is usually simplified as a diagonal inclined strut to facilitate finite element modeling calculations. However, the actual seismic damage and single frame-filled wall pushover experimental results show that when the earthquake shear force is huge, the top of the infill wall and the beam–column connections are usually, thus t...

In this article, we present Defmod, an open source, fully unstructured, two or three dimensional, parallel finite element code for modeling crustal deformation over time scales ranging from milliseconds to thousands of years. Unlike existing public domain numerical code(s), Defmod can simulate deformation due to all major processes that make up the earthquake/rifting cycle, in non-homogeneous m...

Beam-column joints constructed in the pre-seismic building code do not provide transverse reinforcement and good detailing within region. These cause occurrence of brittle shear failure, which is one factors affecting number reinforced concrete (RC) moment resistance structures collapsing during an earthquake. Therefore, this study a beam-column joint with non-seismic was designed strengthened ...

recently, scientists developed the seismic rehabilitation of structures and their points of view were changed from strength to the performance of structures. nonlinear static procedure (nsp) or pushover analysis is a new method that is chosen for its speed and simplicity in calculations. “seismic rehabilitation code” & fema356 considered this method. result of this analysis is a target displace...

Seismic codes were developed to reduce the structural vulnerability and risk associated with earthquakes in earthquake-prone regions of world. The effectiveness code preventing damage is dependent on performance level defined construction technology employed. seismic fragility curves for two recent versions Iran are determined by using hybrid method. probability levels visualized these curves. ...

The experience of the recent earthquakes in Italy caused a shocking impact in terms of loss of human life and damage in buildings. In particular, when it comes to ancient constructions, their cultural and historical value overlaps with the economic and social one. Among the historical structures, churches have been the object of several studies which identified the main characteristics of the s...

The large-scale seismic acquisition system (LSAS) is a kind of field data acquisition system in super scale. It can cover hundreds of square kilometers. To implement the real time transmission of so much data, speed and reliability are the most important criteria of the system. Based on 8b10b code, this paper discusses frame sync technology, error correction code (ECC), and a co-design method o...
