1、混凝土结构设计课程设计任务书09土木工程二班土木教研室2012.5钢筋混凝土现浇楼盖设计一、设计资料：某单层内框架仓库，高为4m。采用现浇钢筋混凝土屋盖，建筑轴线及柱网平面见下图，外墙为370砖墙，偏轴线（内120，外250）。1、屋面为不上人屋面可变荷载标准值0.5。2、钢筋混凝土容重253、屋面保温和构造层总厚度：100mm，自重:1.84、板底为15mm厚水泥砂浆粉刷，重度γ=20。5、材料：混凝土强度等级：见附表钢筋：梁、板中受力筋见附表板中分布筋、梁中箍筋和架立筋采用HPB300。二、设计要求：1、按要求对屋面梁板进行结构布置；其中次梁按纵向布置。2、单向板

2、和次梁按考虑塑性内力重分布计算内力；双向板按塑性理论计算内力；主梁按弹性理论计算内力，绘制出弯矩包络图和剪力包络图。3、对板、次梁、主梁分别进行配筋，完成设计计算书一份（装订顺序：任务书，目录，正文，参考文献）；4、绘制施工图，内容包括：屋盖配筋图；次梁配筋施工图；主梁设计弯矩包络图、抵抗弯矩图及配筋施工图（主梁施工图中应包括钢筋示意图）；施工说明。5、每位同学根据自己学号，取用相应的设计参数：学号L1L2每格板跨数混凝土强度等级板钢筋梁钢筋1600060002C25HPB300HRB4002600060002C30HRB335HRB4003600063002C25H
