Book Inelastic Seismic Response of Reinforced Concrete Buildings with Floor Diaphragm Openings

Download or read book Inelastic Seismic Response of Reinforced Concrete Buildings with Floor Diaphragm Openings written by Mohamed T. Al Harash and published by . This book was released on 2011 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: Floor and roof systems are designed to carry gravity loads and transfer these loads to supporting beams, columns or walls. Furthermore, they play a key role in distributing earthquake-induced loads to the lateral load resisting systems by diaphragm action. In reinforced concrete buildings, the in-plane flexibility of the floor diaphragms is often ignored for simplicity in practical design (i.e., the floor systems are frequently treated as perfectly rigid diaphragms). In recent building standards (ASCE-7, 2005), it is acknowledged that this assumption can result in considerable errors when predicting the seismic response of reinforced concrete buildings with diaphragm plan aspect ratio of 3:1 or greater. However, the influence of floor diaphragm openings (typically for the purpose of stairways, shafts, or other architectural features) has not been considered. In order to investigate the influence of diaphragm openings on the seismic response of reinforced concrete buildings; several 3-story reinforced concrete buildings are designed as a Building Frame System according to the International Building Code (2006). Each building is assumed to be in the Saint Louis, Missouri area, and it's analyzed using IDARC2, a non-commercial program capable of conducting nonlinear analysis of RC buildings with rigid, elastic, or inelastic floor diaphragms, under both static lateral loads (pushover) and dynamic ground motions (time-history), where a suite of three well-known earthquakes is scaled to model moderate ground motions in the Saint Louis region. The comprehensive analytical study conducted involves placing different opening sizes (none, 11%, 15% and 22% of total floor area) in various floor plan locations with respect to the location of the shear walls (located at end frames or at the interior frames), where three types of floor diaphragm models (rigid, elastic, and inelastic) are assumed. Building floor plan aspect ratios of 3:1 and 4:1 are investigated. IDARC2 is enhanced by modifying the fiber model (strain compatibility) computation routine involved in obtaining the idealized moment-curvature curves of floor slabs with openings (symmetric and nonsymmetric). Also, a new option is added so that the user can over-ride IDARC2 idealized moment-curvature curves for slabs with openings and by defining their own. The results are then presented and discussed. It is concluded that in order to capture the seismic response of reinforced concrete buildings with floor diaphragm openings accurately; it is necessary to use an inelastic diaphragm model for floor diaphragm aspect ratio of 3:1 or greater. Thus, using a rigid diaphragm assumption, as specified by ASCE7-05 for buildings concrete floor diaphragms with aspect ratio of 3:1, and elastic diaphragm assumption, as allowed by ASCE7-05 for floor diaphragm with aspect ratio of 4:1, can result in significant underestimations of the lateral loads resisted by the interior building frames and building maximum frame displacements, particularly when the diaphragm openings are located in the middle two-thirds of the building plan. The base shear redistribution due to inelastic slab deformations increases the load subjected to the interior frames significantly. Hence, the influence of inelastic inplane diaphragm deformations due to floor openings cannot be overlooked in such buildings. Simple design recommendation is given for determining proper diaphragm chord reinforcement to prevent in-plane floor slab yielding when openings are present.

Book Seismic Performance of Concrete Buildings

Download or read book Seismic Performance of Concrete Buildings written by Liviu Crainic and published by CRC Press. This book was released on 2012-12-10 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book examines and presents essential aspects of the behavior, analysis, design and detailing of reinforced concrete buildings subjected to strong seismic activity. Seismic design is an extremely complex problem that has seen spectacular development in the last decades. The present volume tries to show how the principles and methods of earthquake engineering can be applied to seismic analysis and design of reinforced concrete buildings. The book starts with an up-to-date presentation of fundamental aspects of reinforced concrete behavior quantified through constitutive laws for monotonic and hysteretic loading. Basic concepts of post-elastic analysis like plastic hinge, plastic length, fiber models, and stable and unstable hysteretic behaviour are, accordingly, defined and commented upon. For a deeper understanding of seismic design philosophy and of static and dynamic post-elastic analysis, seismic behavior of different types of reinforced concrete structures (frames, walls) is examined in detail. Next, up-to-date methods for analysis and design are presented. The powerful concept of structural system is defined and systematically used to explain the response to seismic activity, as well as the procedures for analysis and detailing of common building structures. Several case studies are presented. The book is not code-oriented. The structural design codes are subject to constant reevaluation and updating. Rather than presenting code provisions, this book offers a coherent system of notions, concepts and methods, which facilitate understanding and application of any design code. The content of this book is based mainly on the authors’ personal experience which is a combination of their teaching and research activity as well as their work in the private sector as structural designers. The work will serve to help students and researchers, as well as structural designers to better understand the fundamental aspects of behavior and analysis of reinforced concrete structures and accordingly to gain knowledge that will ensure a sound design of buildings.

Book Effect of Anchorage Slip and Inelastic Shear on Seismic Response of Reinforced Concrete Frames

Download or read book Effect of Anchorage Slip and Inelastic Shear on Seismic Response of Reinforced Concrete Frames written by Jaber Alsiwat and published by . This book was released on 1993 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reinforced Concrete structures located in regions of high seismic activity are expected to develop inelastic deformations in their critical regions. Therefore, inelastic dynamic analysis is required to obtain reliable predictions of structural behavior during an earthquake. Tests on reinforced concrete elements and subassemblages have shown that anchorage slip and inelastic shear deformations can be as significant as those due to inelastic flexure, in the critical regions. Hence, a proper seismic analysis should include inelastic deformations due to anchorage slip, shear and flexure. Flexural response has been researched extensively in the past. Research on the effects of anchorage slip and shear inelasticity is scarce in the literature.
