黑龙江八一农垦大学毕业设计因为梁板为现浇整体,并且各区格为双向板,故直接传给横梁的楼面荷载为三角形和梯形,计算单元范围内的其余荷载通过纵梁传以集中荷载和集中力矩的形式传给横向框架。本工程中边框架的纵梁与柱的轴线不重合,所以作用在框架上的荷载还有集中力矩。竖向荷载作用下框架结构计算简图如图5.2所示。5.2荷载计算(1)⑧轴线框架荷载计算以标准层层和顶层的恒荷载荷载计算为例说明荷载的计算方法,其余的计算过程省略。图5.2中的包括梁重和隔墙的重:标准层:,,,图5.1框架及剪力墙计算单元简图97

黑龙江八一农垦大学毕业设计图5.3竖向恒荷载作用下剪力墙计算简图下面计算恒荷载产生的剪力墙各层集中荷载及集中力矩,为了计算其值,我们先计算5轴线框架的内力,具体的计算方法采用弯矩二次分配法,计算结果见表5.1所示。首先计算5轴线框架-剪力墙的框架在竖向恒荷载作用下的的内力,然后将C端的剪力和弯矩反向施加于剪力墙上再按照静力等效原理将竖向集中荷载和集中力矩移至剪力墙型心处。下面以第一层为例说明计算方法,其余的计算结果见表5.2所示。表5.1竖向荷载作用下⑤轴线框架梁端剪力及柱剪力层次恒荷载作用活荷载作用梁端剪力E柱剪力梁端剪力E柱剪力C端E端C端E端128.3134.322.444.795.950.55228.3134.323.424.795.950.63328.3134.323.424.795.950.63428.3134.323.424.795.950.63528.3134.323.424.795.950.63628.0034.543,574.785.970.63728.2334.313.254.785.970.62828.2434.303.524.785.970.63928.2434.303.414.785.970.631028.2434.303.414.785.970.631128.2834.263.064.805.940.9297

黑龙江八一农垦大学毕业设计,ea取20mm和偏心方向截面尺寸的1/30两者中较大值,即700/30=23mm,故取ea=23mm,因此组内力中水平荷载产生的弯矩值占总弯矩的75%以上,所以柱的计算长度按照下面的方法计算,取柱的计算高度为7.24m。,,故为小偏心受压。取,解方程的到,且。,上式满足要和,否则为构造配筋。本方案中,97 黑龙江八一农垦大学毕业设计所以这组内力计算时为构造配筋。再取轴力最大的一组计算。柱的计算长度的确定和上述的计算结果一致,取值为7.24m。,ea取20mm和偏心方向截面尺寸的1/30两者中较大值,即700/30=23mm,故取ea=23mm,,,故为小偏心受压。取,解方程的到,且和,否则为构造配筋。本方案中,所以这组内力计算时为构造配筋。(3)柱斜截面受剪承载力计算97 黑龙江八一农垦大学毕业设计以A轴第12层柱为例。柱的剪力设计值及相应的轴力设计值为,剪力设计值应满足满足要求。柱的箍筋数量按照公式确定,公式中的由表53查得,其值大于3时取3;N取值为129.77kN()所以按照构造配筋。柱端加密区的箍筋选用4肢。12层柱底轴压比,查表得柱箍筋最小配箍率特征值,则最小体积配箍率:,取值为0.4%满足要求,根据构造要求,取加密区箍筋为,加密区位置及长度按规范要求确定。非加密区还应满足,故箍筋取,各层柱箍筋计算结果见表7.4。各柱均采用井字形复合箍筋表7.4框架柱箍筋数量表柱号层次实配箍筋加密区非加密区A柱1126.31764.842117.52807.70.54φ8@100(0.67)4φ8@150(0.45)4205.581324.311571.32116.70.44φ8@100(0.73)4φ8@150(0.48)1253.021122.24112.321803.60.44φ8@100(0.73)4φ8@150(0.48)C柱1105.541764.842133.22807.70.54φ8@100(1.32)4φ8@150(0.45)4133.911324.311599.62116.70.44φ8@100(1.32)4φ8@150(0.48)97

黑龙江八一农垦大学毕业设计致谢经过二个多月的紧张而又忙碌的学习,终于完成了紧张、忙碌的毕业设计。看到自己辛苦劳动后的成果,心中有许多说不出的感觉。毕业设计是我对四年大学所学知识的第一次综合运用。毕业设计使我学到了许多在书本上学不到的知识,而且这次毕业设计进一步提高了我的设计计算能力,锻炼了我查阅、分析和运用资料的能力。这段时间里,遇到了许多问题,这就使我不得不问老师,去查资料、规范,因此弥补了四年学习的不足,又从中学到了许多知识。四年的学习生活中,我曾经取得了不少的好成绩,与此同时也饱受着困难,挫折和磨难的考验。离别的季节也是收获的季节,看着自己辛勤劳动的成果,自己深敢安慰,我深深知道,成绩不仅是我个人的成果,背后还有老师和同学们的关怀和无私的帮助。整个设计的过程中,老师和同学的帮助下,我不仅对我四年的知识进行了回顾而且也培养了自己独立工作,理论联系实际的能力。当然,在作设计的过程中也看到了自己的缺点和不足之处。就是自己对以前的知识掌握得还不扎实,因此,在以后的工作中我会好好的努力,提高自己的水平。在毕业答辩即将结束之际,我真诚的感谢在设计中指导过我的解恒燕老师和郑鑫老师,没有您的帮助和鼓励我就不能完成这个设计,在设计过程中,通过教研室老师的指点,避免了一些的错误,同时学到了很多知识,特别要感谢解恒燕老师的细心督促,使我的设计顺利的进行。在此,我向所有老师道一声:你们辛苦了!柴冬冬2012.05.97'
