Multi-story, old reinforced concrete (RC) structures with a “soft-story” on the ground floor, sustain considerable damage to soft story during earthquakes due presence of masonry infills in upper stories. Aspects such infill–RC frame interaction are briefly discussed and particular retrofitting scheme for is studied. It consists RC infills, added within bays floor frames combined jacketing surr...

Infilled frames are usually modelled in the context of global building analysis using simplified procedures without considering aspects resulting from interaction between panel and frame. Other aspects, such as adequate design floor beams beam-columns’ joints, control potential sliding shear failure columns, that significantly affect structural response, also typically not accounted for. In pre...

To guide the site staff to produce complex construction products with high quality, this paper proposes a three-dimensional digital technological process method for products. Firstly, information of is processed from perspective quality control and management. Then, geometric entities in product are modeled based on building model (BIM). expressed integrated into by model-based definition (MBD)...

In the present study, friction damper, an energy dissipating passive device is explored to reduce response of open ground storey building under lateral loading due earthquake. This damper installed in selected bays so that reduced. The masonry infill wall macro-modeled form compression only diagonal members. Three different types bracing system were along with Pall – single tension brace cross ...

Currently, the upgrade of existing reinforced concrete (RC) buildings focuses only on energy retrofitting measures due to current policies promoted in scope European Green Deal. However, structural deficiencies are not eliminated, leaving building seriously unsafe despite investment, particularly seismic-prone regions. Moreover, envelopes RC responsible for their efficiency and seismic performa...
