1 section reinforcement method:
在局部或沿构件全长以钢材补强,连成整体使之共同受力;
At the local or along the full length of the component to steel reinforcing, and even the joint force of the whole;
2) 改变计算简图:
2) change calculation diagram:
增设附加支承,调整荷载分布情况,降低内力水平,对超静定结构支座进行强迫位移,降低应力峰值;
Additional support is added to adjust the load distribution, reduce the level of internal force, to statically indeterminate structure bearing forced displacement, reduce the peak stress;
3) 预应力拉索法:
3) prestressed cable method:
利用高强拉索加固结构薄弱环节或提高结构整体承载力、刚度和稳度。
Using high strength cable to strengthen the weak link of the structure or to improve the overall carrying capacity, stiffness and stability of the structure.
