本应用根据国振喜、张树义主编的《实用建筑结构静力计算手册》“桁架的计算”一章编制。可查询、计算各类桁架的杆件长度及内力。 其中包含模块如上述图片显示。 本App为“实用结构静力计算”App的一个大模块,如果您有“桁架”以外的其他静力计算需求,建议选择前者购买。 附原书“桁架计算简述”小节内容: 6.1.1 桁架计算简述 (1) 桁架的内力计算,可假定节点为铰接。将荷载集中于各个节点上,按节点荷载求得各杆杆件的轴向力。 节间荷载对上弦杆所引起的弯矩,在选择杆件截面时再行考虑。 (2) 桁架内力分析时,应将荷载集中在节点上(节间荷载可换算为节点荷载),并假定所有杆件位于同一平面内,杆件重心线汇交于节点中心,且各节点为理想铰,不考虑次应力的影响,这样就可用数解法或内力系数法计算桁架各杆件的轴心力。但当杆件截面高度与其几何长度(节点中心间的距离)之比大于1/10(弦杆)和1/15(腹杆)时,或当钢管杆件截面高度(或直径)与其节间长度之比大于1/12(主管)和1/24(支管)时,则应考虑节点刚性引起的次弯矩。 当桁架上弦有节间荷载时,首先把节间荷载换算为节点荷载,按上弦无节间荷载计算桁架杆件的轴心力。节点荷载换算有两种近似方法:将所有节间的荷载按该段节间为简支的支座反力分配到相邻两个节点上,作为节点荷载;按节点处的负荷面积换算为该节点的集中荷载。两种方法的计算结果差别很小,但后者较为简便。 (3) 求桁架杆件内力时,恒荷载(包括自重)按全跨分布。活荷载除按全跨分布外,尚应根据各种桁架的受力特点,分别按可能出现的不利分布情况进行组合。 (4) 屋面活荷载与雪荷载一般不会同时出现,故取二者之较大者与恒荷载进行组合。 (5) 在一般桁架坡度小于 30°的桁架设计中,对封闭房屋只有当设有天窗时,才考虑风荷载的不利影响。 应用开发过程中已修正原书一些错误,但因公式、数据繁多,代码输入过程中疏漏、错误在所难免,欢迎使用者批评指正。 界面设计简洁直观,功能清晰明了,易用性强。无网络流量消耗。 【免责声明】App只是用来提高设计计算速度的工具。App开发者不对计算结果的正确性与适用性作出承诺。如果将其应用于实际工程,使用者应自行校核并判断计算结果的正确性与适用性。App开发者不承担由此带来的任何直接或间接损失。 如有问题或建议请在AppStore评论中提出或使用以下联系方式。 微博:@结构设计App(关注可有机会获得App免费兑换码) 电子邮件:lrtjqn@icloud.com

Verdict

The call

The clearest difference is in-app purchases: Super Calc Free at none against 桁架设计's 1. Super Calc Free also leads on ads (none vs shown) and review sentiment (50% vs 25%). On price and device support there is nothing between them.
