9409870 Chajes, Michael J. This is a Research Initiation Award. This research involves utilizing the unique properties of composite materials, in combination with engineered wood and concrete, to develop a new, economical, high-strength structural member for use in bridges and buildings. The research will involve the development, testing, and evaluation of concrete-wood-FRP composite beams. the important issues to be addressed are: (1) bond strength between the FRP plates and engineered wood, (2) composite action between and concrete flange and wood web, (3) stiffness, ultimate strength, and ductility of the composite beams, and (4) behavior of the composite beams under sustained loads. The investigation will lead to the development of versatile, high- strength, composite beams and to basic research findings relevant to the use of advanced composite materials for structural engineering applications. ***

9409870 Chajes，Michael J. 这是一个研究启动奖。 这项研究涉及利用复合材料的独特性能，结合工程木材和混凝土，开发一种新的，经济的，高强度的结构构件，用于桥梁和建筑物。 这项研究将涉及混凝土-木材-FRP复合梁的开发、测试和评估。 要解决的重要问题是：（1）FRP板和工程木材之间的粘结强度，（2）混凝土翼缘和木腹板之间的组合作用，（3）组合梁的刚度、极限强度和延性，以及（4）组合梁在持续荷载下的性能。 这项调查将导致多功能，高强度，复合梁的发展和基础研究成果有关的先进复合材料的使用结构工程应用。 ***
