Design and Experimental Investigation of a New-Style Pultruded GFRP Mid-Beam

Earlier laboratory test results showed a possibility of utilizing GFRP beam as a mid-beam in foundation pit support. This paper presents the development of a new-style GFRP mid-beam with I-section and double webs. Loading tests show that the new-style GFRP middle beam can satisfy the requirements for the globe and local stabilities, and simultaneously the material strengths of the middle beam can also be fully utilized. Beam tests with bolted connections show that a combined use of steel bolts and GFRP splice plates improved the stiffness and strength of the beam by 17.9% and 45%, respectively.
