Taking example by typical school buildings, the effect and infective extent of earthquake and basic wind pressure on them are analyzed by comparing the mass collection of reinforcing steel bar with the proportion of concrete in vibration-tolerant and vibration non-tolerant components under the circumstance of basic wind pressure 0.7kN/m2 and 0.35kN/m2, fortified intensity 6, 7 and 8, respectively. The prerequisite and feasibility of upgrading the fortified intensity to vibration tolerance of school buildings are discussed based on the present design specification in structure, and relevant design suggestions and technical steps here should be shared with the persons in architecture to reference and study further.
