摘　　要：消能减震技术是在结构的抗侧力构件中设置消能部件,这些部件通常由阻尼器、耗能支撑等组成。在工业建筑的改造过程中,应用位移型阻尼器柱间支撑既能增加改造结构的刚度也能增加结构阻尼比,还能有效调节结构刚度中心与质量中心的吻合度,避免前两阶阵型的扭转效应。结合具体工程实例说明,由于结构阻尼比的增加而降低了地震作用,减少了上部结构的加固工程量,也减少了地震作用引起的基础加固工程量,并对消能减震技术在工业建筑改造中的应用进行探讨、研究。The technique of energy dissipation and shock absorption applies energy-dissipating parts,such as dampers and energy-dissipating bracings,on lateral-force-resistant members of a construction.In process of industrial construction rebuilding,application of displacement-dependent dampers as column bracing can increase not only rigidity of the rebuilt construction,but also the damp ratio.It can also adjust the coincidence of rigidity centre and mass centre efficiently,thus avoiding torsional effect of the first two mode stages.By increasing damp ratio of the construction,seismic loads go down,which cuts down strengthening work amount as well as foundation strengthening work amount caused by seismic actions.With a specific construction case,the application of energy-dissipating and shock-absorbing technique in industrial construction rebuilding is discussed and analyzed.
