［摘要］對保定垃圾焚燒發(fā)電工程主廠房結(jié)構(gòu)采用時程分析法進(jìn)行地震反應(yīng)分析研究，并對動力特性、位移、加速度等計算結(jié)果進(jìn)行分析。廠房由于設(shè)有垃圾儲存池造成結(jié)構(gòu)剛度在平面、立面都不均勻，且縱向較橫向嚴(yán)重，會產(chǎn)生較大的扭轉(zhuǎn)，不利于抗震。垃圾焚燒工程主廠房結(jié)構(gòu)的抗震設(shè)計應(yīng)合理選擇結(jié)構(gòu)布置方案，采用多個空間有限元分析程序，合理選擇參數(shù)進(jìn)行分析。通過控制振型、結(jié)構(gòu)位移等計算結(jié)果來控制結(jié)構(gòu)的扭轉(zhuǎn)，并適當(dāng)提高抗震措施。

Abstract:The seismic response of the structure system of Baoding refuse incinerating power plant is analyzed and studied by time history analysis method. The calculation results of dynamic properties, displacement and acceleration are concerned. Due to refuse bunker, the stiffness of plant structure is irregular in plane and elevation and the longitudinal direction is more serious than the transverse direction. It makes large torsion and its seismic behavior is poor. The seismic design of main building structure of refuse incinerating power plant should have reasonable selection of structure arrangement scheme, use several special finite element analysis program, select reasonable parameters, control the torsion of structure by controlling calculation results such as vibration mode, displacement and so on and enhance seismic fortification measures properly.
Keywords:refuse incinerating power plant; frame-bent structure; seismic design point; time history analysis
