LOAD EFFECT CALCULATION AND ANALYSIS OF CFRP-OFBG PLATE EMBEDDED REINFORCED CONCRETE BEAM

Abstract

Abstract: CFRP-OFBG slab has good monitoring performance, and the monitoring data can be used to calculate and analyze the load effect of reinforced structures. Based on the plane cross-section assumption and the constitutive relation of stress and strain, a load calculation method for strengthened beams based on CFRP-OFBG slab strain monitoring is presented. The flexural capacity test of 4 CFRP-OFBG slabs embedded reinforced concrete beams was carried out to verify the proposed method. The results show that the calculated value is in good agreement with the test value, and the method is feasible to analyze the real-time load effect of reinforced beams.

Key words: CFRP-OFBG slab, reinforced concrete beam, embedded reinforcement, load effect
