项目摘要
9810005 Hajjar This project presents a combined computational/experimental effort focusing on the seismic behavior of the interface between concrete walls and steel frame members in composite wall structural building systems. The work targets the development of comprehensive, nonlinear, static and dynamic analysis procedures for modeling composite wall building structures, including the behavior of the steel/concrete interface; and achieving a more through understanding of the composite cyclic interaction between RC walls and steel framing. Composite structural wall systems provide excellent strength and stiffness to withstand both service level drift and ultimate forces from seismic events. The objectives of the research include the development of a finite element formulation for the seismic analysis of composite reinforced concrete walls with surrounding steel framing, the quantification through experimental testing of the combined cyclic shear and tensil strength of headed hear studs and deformed bar anchors embedded in concrete panels, and the verification and calibration of the shear and axil strength interaction relations under monotonic and cyclic loading for connectors used in practice used in practice. A three-dimensional, nonlinear finite element to model to simulate the cyclic interaction at the steel/concrete wall interface will be formulates. A series of experiments will be designed to document the cyclic interaction along the interface between RC walls and surrounding steel framing. The analyses will feature a geometrically and materially nonlinear finite element formulation, using a new fiber-based finite element for the shear connectors and appropriate continuum elements for the concrete in the interface region, align with stress-space plasticity formulations for both the concrete and steel. The ultimate goals is the development of clear guidelines for: 1) incorporating the steel-concrete interface behavior in both linear and nonlinea r analyses of composite wall systems; and 2) detailing the steel frame-concrete panel connection to achieve desirable performance goals. This project is supported under the fourth year competition of NSF 94-154. ***
9810005 Hajjar该项目提出了一个结合计算/实验的努力,重点是在复合墙结构建筑系统中混凝土墙和钢框架构件之间的界面的抗震性能。 这项工作的目标是全面的,非线性的,静态和动态的分析程序建模复合墙建筑结构的发展,包括钢/混凝土界面的行为,并实现了更深入地了解钢筋混凝土墙和钢框架之间的复合循环相互作用。复合结构墙系统提供了优异的强度和刚度,以承受来自地震事件的服务水平漂移和极限力。 研究的目标包括:建立一个用于周边有钢框架的钢筋混凝土组合墙抗震分析的有限元公式,通过试验测试定量分析嵌入混凝土板中的有头螺栓和变形钢筋锚栓的组合循环剪切和拉伸强度,以及在单调荷载和循环荷载作用下,对实际使用的连接件的剪切和轴向强度相关关系进行了验证和标定。 建立了一个三维非线性有限元模型,模拟钢/混凝土墙界面的循环相互作用。 一系列的实验将被设计来记录循环相互作用沿着之间的界面钢筋混凝土墙和周围的钢框架。 分析将采用几何和材料非线性有限元公式,使用新的纤维为基础的有限元剪力连接件和适当的连续体元素的混凝土在界面区域,对齐与应力空间塑性公式的混凝土和钢。 最终目标是制定明确的指导方针:1)将钢-混凝土界面行为纳入组合墙系统的线性和非线性分析; 2)详细说明钢框架-混凝土面板连接,以实现理想的性能目标。 该项目得到了NSF 94-154第四年竞赛的支持。 ***
