Name: Instructor's name: Course: Date: Seismic Analysis and Response of Bare and Masonry-Infilled Reinforced Concrete Frame Structures Part One: Introduction Multi-storey structures are constructed with infills of bricks or concrete blocks. These infills are functional to the structures that act as a single unit to the structure when connected to the frame…
Extract of sample
Since the infill walls play some roles during earthquakes, their design need consideration to withhold lateral forces. From a research conducted out, most concrete structures succumb to seismic loads due to: Failures of beam-column joints as a result of poor reinforcement at the joints and/or poor workmanship in installation of reinforcement beams; Basic failure that results from flexural weakness and or low shear strength; Failure of the infill wall that results from enough shear strength or a flexural strength that is out-of-plane (Griffith, Mike 2008, p.2). The relationship between un-reinforced masonry in-fills and reinforced concrete has led to unique influences in comparison to bare frames or seismic response. The behaviour of the in-fills to seismic loads remains controversial for existing buildings (Magenes, Guido and Pampanin Stefano, 2004). The issues to be addressed are modelling of structural elements and masonry in-fills panels. The analysed model need validation in terms of Beam-Column Subassemblies, single storey frames with infills, Dimension Frame with infills for multi-storey structures. Limitations related to infill panels and joints area also considered (Magenes, Guido and Pampanin Stefano, 2004). ...
