They are mainly single cross-frame, beams and columns inadequate bearing capacity, structural measures does not meet the requirements. The feasibility of energy dissipation reduction design to solve these problems was analyzed, and the structural design principle of energy dissipation was expounded. A classroom building which using the reinforcement of the viscous fluid dampers, seismic action decreases by about30%, basically meet the seismic fortification intensity to reduce the yearly requirements,so that the original texture and structure measures can meet the specification requirements without using other measures.Keywords: structural reinforcement; energy dissipation; viscous fluid damper; frame structure; teaching building
