Development of Bolted End Plate Connections for Steel Reinforced Concrete Composite StructuresAbstract (press-release format for general public) The most significant lesson learned from the 1994 Northridge earthquake and the 1995 Kobe earthquake was the cracking and brittle failure of welded moment connections of modern steel buildings. The structural engineering communities have since been working on development of improved designs. One possible solution for making steel structures more resistant to earthquakes is to combine concrete and steel to take the advantages of each material. Professors Xiao and Anderson at the University of Southern California have conceived several new details to achieve this. They proposed to use bolted steel and concrete composite connections instead of traditional welded connection to improve constructability and meanwhile to ensure excellent seismic behavior for building structures. In the proposed project, they plan to prove their ideas through experimental testing and analysis.

型钢混凝土组合结构螺栓端板连接的发展摘要（公众新闻稿格式）从1994年北岭地震和1995年科比地震中吸取的最重要的教训是现代钢建筑焊接弯矩连接的开裂和脆性破坏。此后，结构工程界一直致力于开发改进的设计。使钢结构更加抗震的一个可能的解决方案是将联合收割机混凝土和钢结合起来，以利用每种材料的优点。南加州大学的肖教授和安德森教授设想了几个新的细节来实现这一点。他们建议使用螺栓钢和混凝土组合连接代替传统的焊接连接，以提高可施工性，同时确保建筑结构具有良好的抗震性能。在拟议的项目中，他们计划通过实验测试和分析来证明他们的想法。
