9、凝土结构设计规范（GB 50010-2002）11.4.9规定，考虑地震作用组合的框架柱抗震受剪V1/RE1.05ftbh0/（+1）+fyvAsvh0/s+0.056N，经验算截面，截面均符合规范要求；7. 根据混凝土结构设计规范（GB 50010-2002）表11.4.12-2规定，二级抗震下柱箍筋加密区箍筋最大间距为纵向钢筋直径的6倍和100中的较小值，故取间距为100mm，最小直径为8mm，因此设10100加密箍筋，而柱非加密区箍筋数量须大于50%加密区的配箍量，则非加密区设10150箍筋；根据混凝土结构设计规范（GB 50010-2002）11.4.14规定，框架柱的加密区长度应取柱

10、截面的长边尺寸、柱净高的1/6和500mm的最大值，所以，本设计框架柱加密区长度取为800mm；8. 经验算，配筋率均满足最小配筋率要求。第八节 楼板计算（只计算第三层楼板）一、楼板计算方法的确定:根据混凝土结构设计规范（GB50010-2002）规定，计算本层楼板时，将长短边之比小于2.0的楼板视为双向板，将长短边之比大于2.0的楼板视为单向板，楼板的编号见楼板计算简图（图8-1）。为充分利用混凝土考虑塑性内力重分布，单向板采用弯距调幅法计算，双向板采用塑性绞线法计算。本层楼板与梁整浇，四边固端。采用C35混凝土， N/mm2，钢筋采用HRB335，=300N/mm2，保护层厚板底为15mm

11、，板顶为20mm。板厚为100mm，部分为120mm，板底=20mm，板顶=25mm。二、单向板计算：弯距调幅法就是对结构按弹性理论所算的弯距值和剪力值进行适当的调整。与梁整浇连续单向板考虑塑性内力重分布的弯距计算系数取值见表8-1：弯距计算系数取值表 表8-1截面位置端支座边跨跨中离端第二支座离端第二跨跨中中间支座中间跨跨中两跨连续三跨以上连续-1/161/14-1/10-1/111/16-1/141/16板计算跨度，和为板下支承梁宽度，由于板1和板2、板3和板4的跨度差值小于10%，因此可将（1）（2）轴、（2）（6）轴、（8）（11）轴、（11）（12）轴内的单向楼板以及（6）（8）轴的

12、部分单向楼板视为等跨连续板，取m板宽计算。支座及跨中截面弯距用弯距系数法求，该系数已考虑塑性内力重分布，。按规范要求，梁板整浇时，板上构造钢筋直径大于8mm。对二级钢，时，取，。单向板计算过程见表8-2。表中，N/mm2。 单向板计算表 表8-2板格号截面位置 （mm）（mm） （mm）（mm）恒载 （kN/m）活载 （kN/m）1.35恒+0.7 1.4活弯距系数（kN/m） （mm）计算配筋（mm2）配筋实际配筋（mm2）1支座300250240021253.5048.65-0.063-2.44750.02600.026417.5010150523跨中250250240021503.504

18、，建立外荷载与作用在塑性绞线上的弯距之间的关系，从而求出各塑性绞线上的弯距，以此作为各截面的弯距设计值。本楼层双向板可用塑性绞线法计算。混凝土采用C35，钢筋采用HRB335， =300N/mm2。楼板有效高度短边方向为80mm，长边方向为70mm。为楼板的短边方向长度，为长边方向长度。由于所有楼板均与梁柱整浇，所以考虑板跨内起拱作用，凡中间跨板的跨中截面及中间支座截面以及边跨板的跨中截面及楼板边缘算起的第二个支座 截面弯距均折减20%。（10）和（11）号楼板板厚为120mm，其余为100mm。板底保护层为15mm，板顶为20mm。双向板配筋时也按1m板宽配筋。对二级钢，时，取，。双向板弯距
