Abstract

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
