To study the effects of infill wall on progressive collapse resistance reinforced concrete (RC) frames with slabs, a macro finite element (FE) model was built using general purpose software OpenSees. The FE validated by existing test results. Then, subsequently used to predict potential eight-story RC frame including slabs and walls. numerical studies demonstrated that inclusion walls could inc...

The present study investigates the seismic performance of twelve-story RC buildings focusing on structural effects flat walls which are commonly neglected in design practice. Two-span moment-resisting frame was numerically modeled considering three analytical cases: Case 0 beam-column subassembly, 1 with conventional walls, and 2 damage control were proposed authors’ previous study. Comparing m...

Hybrid steel and concrete seismic-resistant systems made by frames with reinforced infill walls (SRCWs) have potential advantages over structural solutions only or (RC). In fact, the high initial stiffness of is useful to minimize damage non-structural elements under frequent (low moderate) earthquakes while ductility dissipative capacity allow good performances rare (high-intensity) events. Eu...

Since reinforced concrete (RC) buildings have long service life, cutout openings are generally needed in their load-bearing walls as a sustainable solution order to meet new requirements of users. However, the decrease capacity walls, which may result failure buildings. In this paper, we investigate possibility making door opening RC wall an existing building Gävle Sweden. The studied current p...

In-plane lateral loading tests were conducted to investigate the structural performance of SFRC shear walls. The test results revealed that steel fiber reinforcement mitigated damage walls and enhanced their capacity. number cracks on at an interstory-drift angle 1/200 was twice as significant RC wall, maximum residual crack widths approximately half. Shear stiffness degradation after cracking ...

OBJECTIVE This study investigates the effects of Nd:YAG laser irradiation combined with different irrigation protocols on the marginal seal of root fillings. BACKGROUND DATA Limited information exists regarding the effects of morphologic changes to root canal (RC) walls after Nd:YAG laser irradiation after smear-layer removal with EDTA on the sealing ability of root fillings. METHODS The 75...
