The infill walls are typically connected to \u003Cbr \/\u003Ethe RC frame with cast-in-place dowel reinforcement along one or more edges of the wall. \u003Cbr \/\u003EThere is limited guidance in masonry codes to design these types of structures, and their \u003Cbr \/\u003Eseismic performance has not been characterized with experimental tests. In this work, an \u003Cbr \/\u003Eexperimental program characterized the seismic behavior of hybrid concrete-masonry frames \u003Cbr \/\u003Eand showed they do not exhibit the typical strut mechanism observed in unreinforced masonry \u003Cbr \/\u003Einfill structures. In addition, a detailed finite element modeling scheme and calibration \u003Cbr \/\u003Emethodology was developed for modeling partially grouted masonry. This model includes a \u003Cbr \/\u003Enovel calibration method to account for the difference in the shear and tensile behavior of \u003Cbr \/\u003Egrouted and ungrouted bed joints, and a method to account for the contribution of vertical \u003Cbr \/\u003Ereinforcement to the shear capacity of the grouted bed joints. Finally, simplified models were \u003Cbr \/\u003Eproposed for use in engineering design. The adaptation of the TMS 402 strut model for hybrid \u003Cbr \/\u003Econcrete-masonry is suggested to incorporate the effects of the masonry infill and connections in large models.\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Seismic Performance, Analysis, and Design of Hybrid Concrete-Masonry"}],"uid":"28077","created_gmt":"2014-11-10 14:56:53","changed_gmt":"2016-10-08 02:10:13","author":"Danielle Ramirez","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2014-11-19T08:00:00-05:00","event_time_end":"2014-11-19T10:00:00-05:00","event_time_end_last":"2014-11-19T10:00:00-05:00","gmt_time_start":"2014-11-19 13:00:00","gmt_time_end":"2014-11-19 15:00:00","gmt_time_end_last":"2014-11-19 15:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"1808","name":"graduate students"},{"id":"100811","name":"Phd Defense"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
