2、tressing bolt and the contrast against it by bonding steel plate by the means of theoretics and experiment. Through this study, the author induces many valuable conclusions First，the author car

3、ried out static experiment of fixed support beam strengthed by prestressing bolt and by bonding steel plate. In this experiment, there are five beams, all these beams got true shear cracks by
