There are three main ways:
1) section reinforcement method: in the local or along the full length of the component, steel is strengthened to make the whole joint force.
2) Change the calculation sketch: add additional support, adjust the load distribution, reduce the internal force level, force displacement of the statically indeterminate structure support, reduce the peak stress;
3) Prestressed cable method: using high-strength cables to reinforce weak links or improve the overall bearing capacity, stiffness and stability of the structure.
