The seismic performance of RC columns could be significantly improved by continuous spiral reinforcement as a result of its adequate ductility and energy dissipation capacity. Due to post-earthquake brittle failure observations in beam-column connections, the seismic behaviour of such connections could greatly be improved by simultaneous application of this method in both beams and columns. In ...

In another work, the “open safe” of the HAZUS-MH methodology was cracked to create seismic vulnerability functions that honor all HAZUS-MH methodologies and data, yet that appear in the form of tables of mean casualty rates (indoor deaths and injuries as four fractions of total occupancy) versus a structure-independent intensity measure, in particular, Sa 0.3 sec,5% or Sa 1.0 sec,5% . In this w...

Article history: Received: 14.5.2014. Received in revised form: 20.1.2015. Accepted: 14.5.2015. In order to determine the deformation capacity of reinforced concrete composite shear wall with concealed bracings at different performance levels, some previous research of domestic scholars are reviewed by analyzing 89 shear wall specimens using a performance-based seismic design method. The perfor...

For the first time, 2018 edition of Turkish Building Earthquake Code has added a dedicated chapter for design high-rise buildings in earthquake-prone areas. Keeping view widely practised option rigid shear walls at centre structure, latest code additionally defined limits shear-wall axial forces buildings. The new force have not been independently investigated optimal and criticality. This call...

This is the second paper in a two-part series that describes a massively parallel code that performs 2D full-waveform inversion of wide-aperture seismic data for imaging complex structures. We present several numerical validation of the full-waveform inversion code with both canonical and realistic synthetic examples. We illustrate how different multiscale strategies can be applied by either su...

This paper examines differences in performances of a range of torsionally stiff and flexible single story buildings designed with the provisions of Iranian Standard 2800. Seismic nonlinear dynamic time history behavior of eight building models subjected to seven horizontal bi-directional design spectra compatible ground motions are investigated. These models cover a wide range of very torsional...

The simulation of damage process of high arch dam subjected to strong earthquake shocks is significant to the evaluation of its performance and seismic safety, considering the catastrophic effect of dam failure. However, such numerical simulation requires rigorous computational capacity. Conventional serial computing falls short of that and parallel computing is a fairly promising solution to t...

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...

Abstract This article contains an edition of a 17th-century Low German letter addressed to the congregation in Stockholm. Seen against shift writing language from High German, this is analyzed respect code-mixing, which shown fulfill communicative function. Furthermore author here suggests that code-mixing observed can be described as congruent lexicalization, where syntactic structures are fil...
