Innovative Composite Slab and Beam Floor Systems

这项研究的总体目标是为钢框架建筑开发比目前使用的更高效的新楼板系统设计。这种效率将通过增加组合板跨度和框架重量以及开发集成设计来实现，该设计将结构、电气、机械和通信系统整合到部分预装的配置中。研究的目标将通过设计、分析和实验的综合方法来实现。潜在的大跨度组合板体系将使用部分组合理论进行评估，该理论结合了基本试验和非线性有限元程序。与界面粘结和端部锚固强度相关的基本楼板性能将通过基本试验进行评估。将开发半刚性组合梁-梁连接，以减少与使用高强度钢相关的适用性问题。

The general objective of the research is to develop new floor system designs for steel framed buildings that are more efficient than those currently used. This efficiency will be achieved through a combination of increased composite slab spans and framing weight and development of integrated designs that incorporate structural, electrical, mechanical and communication systems in a partially pre-assembled configuration. The objectives of the research will be achieved by using an integrated approach of design, analysis and experimentation. Potential long-span composite slab systems will be evaluated using partial-composite theory, which incorporates elemental tests and a non-linear finite element program. Basic slab properties related to the interfacial bond and end-anchorage strengths will be evaluated with the elemental tests. Semi-rigid composite beam-to-girder connections will be developed to reduce serviceability problems associated with the use of high strength steels.
