The engineering disposal of longitudinally and staggered layout for the external tendon in reinforcement engineering, which will promote the integral structureductility.
在加固工程中，体外预应力筋纵向交错布筋的设置，能提升结构的整体延性。

Based on the piers mode shape function, this paper studied the methodology of structureductility coefficient by modal test and the procedure of the structures inelastic seismic force.
In normal cases, steel reinforced concrete structure is able to resolve this problem, but sometimes it is necessary to use SRHSHPC to meet bearing capacity and ductility requirements.
