| Abstract: | This paper discusses application of glass-fiber-reinforced plastic(GFRP) in a foundation pit support instead of conventional material.The laboratory studies on the mechanical properties of the GFRP beams with different sections were carried out.Their mechanical behavior and the failure features are described and analyzed.The test results indicate that the material properties and the stability of the GFRP middle beam and the local strength at the joint between web and flange are the main factors in the compo... |
