目前,国内燃煤机组发电厂主厂房大量采用现浇框架结构横向抗侧力体系,为配合燃煤机组发电工艺与设备安装,主厂房框架结构具有纵向开间大、横向跨度大和层高大等特点。纵向开间一般达到10 m或以上,柱横向跨度一般在10~14 m之间。燃煤机组发电厂主厂房由除氧间与煤仓间构成,主厂房各楼层之间标高跨度大(图1),其中煤仓间分别布置有磨煤机层(0.000 m)、煤斗运转层(约17.000 m)、煤斗梁层(约33.000 m)、皮带层(约42.000 m),煤仓间屋面高度大约
At present, the main plant of domestic coal-fired generating units adopts a large number of horizontal anti-lateral force systems of cast-in-situ frame structures. In order to support the power generation technology and equipment installation of coal-fired units, the main plant frame structure has the features of large vertical opening, large horizontal span and tall floors. Longitudinal open space generally reach 10 m or more, column horizontal span is generally between 10 ~ 14 m. The main plant of a coal-fired generating unit is composed of a deoxygenation chamber and a coal storage chamber. The elevation between the various floors of the main plant is large (Figure 1). The coal storage is arranged with a coal mill (0.000 m) (About 17.000 m), coal bucket (about 33.000 m), belt (about 42.000 m), roof height between coal bunkers
