摘要/Abstract

摘要： 提出了一种基于复合材料拉挤型材的新型高层建筑外挂构架梁。结合实际工程问题,设计并制备了大尺寸拉挤型材外挂构架梁,通过有限元数值模拟分析验证了拉挤型材构架梁的力学性能。对构架梁的安装施工方法进行了介绍,并和传统钢结构方案进行了经济性比较。提出的拉挤型材外挂构架梁可以大幅降低结构自重(仅为同类型钢结构的四分之一),提高结构的环境耐腐性能,并有效减少施工相关的措施费。

Abstract: A new type of external frame beam for high-rise buildings is proposed based on pultruded glass fiber reinforced polymer (GFRP) composite profiles. Combined the practical engineering problems, the external hanging frame beam of large size pultruded profiles is designed and prepared. In addition, a series of finite element analyses were conducted to evaluate and validate the mechanical performance of proposed GFRP beam. Then, the installation/construction method was introduced in detail. Last but not least, the proposed GFRP frame beam was compared with steel counterpart in terms of the material usage and economic performance. It is observed that the proposed GFRP frame beam is able to reduce the self-weight of the frame structure by 75%, improve the environmental durability of the structure and decrease the construction-related costs.

Key words: pultruded FRP profiles, high-rise buildings, external frame beam
