摘　　要：在保证面内受弯玻璃肋板平面内稳定的前提下,采用玻璃板条对玻璃肋板进行加固,通过对原玻璃肋板和玻璃加固玻璃肋板的极限承载试验的研究,分析了构件加固前后试件破坏的荷载-位移曲线及破坏机理,验证了该加固方法的可行性。试验结果表明,加固后玻璃肋板较加固前肋板的承载力提高28.9%,说明该方法可以有效改善玻璃肋板的受力性能,提高玻璃肋板的极限承载力。但加固后玻璃肋板,原玻璃肋仍为主要承力者。On the basis of the stability of the in-plane bending glass plate rid,using the glass lath to reinforce the glass plate rid,the stress response to the load is tested,the load-displacement curve after buckling is analyzed and the feasibility of this reinforced method is judged.The results of the test show that the load of the reinforced ones can increase 28% comparing with the unreinforced one.The glass plate rid which is damaged earlier than the glass for reinforcing commits the main force.This paper also provides a guide for the future design for the glass plate rid ＇s reinforcement.
