[下载][软件][结构设计] BeamWebRebarNum: RC梁的构造腰筋计算工具 [Calculation tool of waist reinforcement for RC beam]

实干、实践、积累、思考，创新！ 之前写的小工具，整理分享给大家。 程序图标 ( Program Icon ) 程序介绍 ( Program Introduction) 根据 GB50010-2010 混凝土结构设计规范 计算钢筋混凝土梁的构造腰筋。 规范条文： 6.3.1 矩形、T形和I形截面受弯构件，截面腹板的高度hw：矩形截面，取有效高度；T形截面，取有效高度减去翼缘高度；I形截面，取腹板净高。 9.2.13 梁的腹板高度hw不小于450mm时，在梁的两个侧面应沿高度配置纵向构造钢筋。每侧纵向构造钢筋(不包括梁上、下部受力钢筋及架立钢筋)的间距不宜大于200mm，截面面积不应小于腹板截面面积(bhw)的0.1％，但当梁宽较大时可以适当放松。 此处，腹板高度hw按本规范第6.3.1条的规定取用。 程序界面 ( Program Interface ) 下载 ( Download ) (  如果需要这个软件，请在评论区留下您的评论，软件会发送到您的评论邮箱，敬请尊重劳动成果 ！！)   (大家注意评论邮箱要填写正确，后台自动发送软件，如果邮箱填写错误，会发送不到。) 相关软件资料 ( …

[笔记][结构][设计] 钢管与钢管混凝土截面的刚度差多少？(What is the difference in stiffness between steel tube and concrete-filled steel tube section)

实干、实践、积累、思考，创新。 钢管填充混凝土能提高截面的刚度，这个是大家都知道的，也是实际项目中遇到刚度不够时候常常采用的招，那到底从钢管截面变为钢管混凝土截面，刚度能提高多少？似乎平时都没有具体算过。以下就搞个简单截面，定量算算。(What is the difference in stiffness between steel tube and concrete-filled steel tube section?) 钢管截面 Steel tube section 钢管混凝土截面 Concrete-filled steel tube section 混凝土截面 Concrete Section CFT截面的刚度增大了多少? 等效截面的刚度计算公式： EI …

[论文][Paper]Deformation Limits of L-Section RC Shear Walls (L形RC剪力墙的变形指标)

In order to establish the relation between damage state and member deformation of the L-section RC shear wall, 216 FE models designed to meet the requirements of the Chinese codes were set up. The analysis fully considers the variation of parameters including axial load ratio and shear span ratio etc. According to the results, criteria of classifying failure modes of L-section RC shear walls are proposed. Failure modes are determined by shear-span ratio, moment-shear ratio and end columns’ reinforcement ratio. Deformation limits corresponding to respective performance levels are put forward. Fitted formulas of calculating the limits are also presented. It is shown that the categorization criteria are reliably accurate in predicting failure modes. Deformation limits of a given L-section RC shear wall could be determined via axial load ratio and moment-shear ratio. The fitted formulas possess a satisfactory correlation with numerical results.
