The objective is to develop a lightweight, adjustable, maintenance-free as well as economical structural system for use in the construction industry. To be studied is a prestressed structural system of kevlar 49 and E-glass polyester resin, which have excellent corrosion resistance as well as being lightweight. The objective of the research will focus on the time-dependent characteristics of the beam elements of the proposed system and the feasibility of developing a computer model which can predict the behavior of these elements. The Phase I effort will involve an investigation into 3 major areas; materials, geometry, and construction. The time-dependent studies will involve full-scale testing of the proposed beam elements at the Center for Advanced Technology for Large Structural Systems (ATLSS) under Dr. John W. Fisher, Director, at Lehigh University. Phase II will involve full-scale dynamic tests at the ATLASS Center.

其目标是开发一种轻型、可调节、免维护和经济的结构系统，用于建筑行业。本文研究的是一种由凯夫拉尔49和e -玻璃聚酯树脂组成的预应力结构体系，该体系具有优异的耐腐蚀性和轻质性。研究的目标将集中在拟议系统的梁单元的时间依赖特性和开发一个计算机模型，可以预测这些元素的行为的可行性。第一阶段的工作将涉及对三个主要领域的调查；材料、几何和构造。这项与时间相关的研究将包括在里海伊大学（Lehigh University）主任John W. Fisher博士领导的大型结构系统先进技术中心（ATLSS）对拟议的梁元件进行全面测试。第二阶段将在ATLASS中心进行全面动态测试。
