本方案称号为荣资商城2号楼,位于包头市钢铁年夜巷北，构造范例主体2㎡，一层层高5.4m，二层层高4.5m，三～六层层高为3.3m，一～二层为商场，三～六层为办公楼.室表里高差450mm，修建物总高度24m。 按照屋宇布防烈度、构造范例跟屋宇高度，该六层框架构造断定为抗震烈度为八度，抗震品级为二级，方案运用年限50年，修建防火品级为二级，修建耐火品级为二级，持久年限为二级，平安品级为二级，构造的主要性系数取1.0。 在进展框架构造方案时，进展层间荷载代表值的盘算，用极点位移法求出自震周期，按底部剪力法盘算程度地动荷载感化下的内力，用弯矩调配法盘算竖向荷载感化下的构造内力，并通过内力组合寻出最倒霉内力组合，进展框架柱、框架梁的截面、配筋方案。还计罢了次梁、楼梯的荷载，进一步进展了截面、配筋的盘算,并进展了柱下独破根底的盘算. 要害词工程概略盘算前提框架构造 Abstract ThenameofthedesignofthesecondbuildingofaRongzimall,BaotouIronandSteellocatedintheNorthMainStreet,Structuretypeselectionbasedonsixmainframe,atotalconstructionareaof5042.52㎡,ahigh-level5.4 m,Twolayersof4.5 mhigh,three~sixlayersof3.3 mhigh,oneandtwolayersshoppingcenter,Three-sixlayersofficebuilding,Indoorandoutdoor450 mmheightdifference,Buildingheight24 m.
