CLT panels have been investigated for reinforcement of existing masonry-infilled RC framed buildings through the increase overall lateral stiffness structure, thus reducing story drift demand. The contribution depends on connection to frame elements. This paper evaluates role connectors by which is attached frames capacity, ductility, and energy dissipation structure its elements separately usi...
Acquisition and processing of multifold groundpenetrating radar (GPR) data enable detailed measurements of lateral velocity variability. The velocities constrain interpretation of subsurface materials and lead to significant improvement in image accuracy when coupled with prestack depth migration (PSDM). Reflection tomography in the postmigration domain was introduced in the early 1990s for vel...
Late Quaternary separation of Britain from mainland Europe is considered to be a consequence of spillover of a large proglacial lake in the Southern North Sea basin. Lake spillover is inferred to have caused breaching of a rock ridge at the Dover Strait, although this hypothesis remains untested. Here we show that opening of the Strait involved at least two major episodes of erosion. Sub-bottom...
The over-strength coefficient is one of the key factors for seismic safety a structure. For RC frames, infill wall may improve lateral bearing capacity, while demand increases as well, which leads to unexpected performance an infilled frame in past earthquakes. Therefore, it necessary systematically study effect frames from point capacity and demand. In this paper, 36 structures with/without wa...
استفاده از دیوار و پارتیشن در ساختمان سازی اجتناب ناپذیر می باشد در ساختمانهای تجاری و اداری و مسکونی بخاطر توزیع فضای داخلی آپارتمان از این دیوارها استفاده می شود. در این پایان نامه سعی می شود که اثر دیوار بر رفتار سازه ای ساختمان در نظر گرفته شود. ابتدا تاریخچه بررسی تاثیر دیوار بر رفتار سازه ای ارائه شده است و در ادامه مدلهای سازه ای که رفتار یکپارچه قاب و میانقاب را بیان کند، بیان می شود. د...
Ductile RC frames are often considered to have superior seismic performance even with infills. However, the of this type structure needs be reassessed considering additional shear requirements produced by infills-column interaction and increased hazard due impact infills on vibration period structure. This paper presents a performance-based earthquake engineering framework aimed at assessment c...
