the static load test was done on the frame beam strengthened by cfrp with frame joint anchored in different mode, and the bearing capacity, deflection and width of crack was surveyed.
frame joint is the key part connecting beams with columns.
节点是连接梁和柱的关键部位,梁和柱的内力通过节点传递。
the text used exact method of elasticity, set up stress function about frame joint indiffereut position, found theoretical formula of stress distribution and made simple analysis.
