摘要

抗震设计理念寻求(a)无损坏,(b)无重大结构损坏,以及(c)在轻微、中度和重度地震震动下,正常建筑无重大结构损伤但不倒塌。提出了低层钢筋混凝土特殊弯矩框架建筑的抗震设计程序,符合这一思想;通过适当的尺寸和加固细节,建筑物被设计成具有延展性,这样它们就可以在不倒塌的情况下抵抗严重的地震震动。研究建筑物的非线性分析用于定量确定(a)确保正常建筑物抵抗严重地震震动所需变形能力所需的设计参数范围,(b)代表不同结构损伤状态开始的四个特定极限状态,以及(c)哲学中所述的轻微和中度地震震动水平,以及与无倒塌的结构损伤状态相关的极端地震震动水平。已确定的结构损伤状态的四个极限和地震震动的三个级别与文献中基于性能的设计指南一致。最后,利用非线性分析结果验证了所提出程序的有效性。

Design of RC moment frame buildings consistent withearthquake resistant design philosophy
Earthquake Resistant Design Philosophy seeks (a) no damage, (b) no significant structural damage, and (c) significant structural damage but no collapse of normal buildings, under minor, moderate and severe levels of earthquake shaking, respectively. A procedure is proposed for seismic design of low-rise reinforced concrete special moment frame buildings, which is consistent with this philosophy; buildings are designed to be ductile through appropriate sizing and reinforcement detailing, such that they resist severe level of earthquake shaking without collapse. Nonlinear analyses of study buildings are used to determine quantitatively (a) ranges of design parameters required to assure the required deformability in normal buildings to resist the severe level of earthquake shaking, (b) four specific limit states that represent the start of different structural damage states, and (c) levels of minor and moderate earthquake shakings stated in the philosophy along with an extreme level of earthquake shaking associated with the structural damage state of no collapse. The four limits of structural damage states and the three levels of earthquake shaking identified are shown to be consistent with the performance-based design guidelines available in literature. Finally, nonlinear analyses results are used to confirm the efficacy of the proposed procedure.

期刊介绍: The Earthquakes and Structures, An International Journal, focuses on the effects of earthquakes on civil engineering structures. The journal will serve as a powerful repository of technical information and will provide a highimpact publication platform for the global community of researchers in the traditional, as well as emerging, subdisciplines of the broader earthquake engineering field. Specifically, some of the major topics covered by the Journal include: .. characterization of strong ground motions, .. quantification of earthquake demand and structural capacity, .. design of earthquake resistant structures and foundations, .. experimental and computational methods, .. seismic regulations and building codes, .. seismic hazard assessment, .. seismic risk mitigation, .. site effects and soil-structure interaction, .. assessment, repair and strengthening of existing structures, including historic structures and monuments, and .. emerging technologies including passive control technologies, structural monitoring systems, and cyberinfrastructure tools for seismic data management, experimental applications, early warning and response
