Jacket platform was assumed as steel frame structure and the pile-soil-structure interaction was considered. Optimum method was applied to aseismic design of structure.
The thickness of a panel zone has a direct influence on the stiffness, strength and deformation steel moment resisting frame, by which the aseismic performance of a frame is also affected.
节点域的厚度直接影响着节点的刚度、强度和变形，从而影响框架的抗震性能。

The unbonded prestressed concrete flat beam frame can meet the aseismic requirement.
