本课程名为“中高层建筑风荷载计算设计”，旨在详细清晰地解释如何计算中高层建筑的风压和底部弯矩。课程以澳大利亚/新西兰标准AS1170.2为基础，但核心概念适用于其他规范。 课程将从风荷载的基本概念讲起，随后通过实际案例，逐步展示如何从规范中获取计算风荷载所需的各项参数，包括： * **区域风速**：针对不同地区的风速进行说明。 * **地形/高度修正系数**：解释不同地形类别的定义。 * **建筑重要性级别与回风期**：根据建筑使用情况和人员占用确定。 * **风向修正系数** * **山形修正系数** * **遮蔽修正系数** * **场地风速** * **设计风速** * **气动形状系数**：针对建筑不同表面（迎风面、背风面、侧面、屋顶）和构件（墙体、屋顶覆盖层）进行详细计算，涉及外压、内压、面积折减、局部压力、女儿墙修正、荷载组合以及动力响应等因素。 通过以上参数的计算，课程将进一步推导出： * **双向净风压**：针对垂直于风的方向计算。 * **底部弯矩**：由风压产生的结构底部弯矩。 * **覆盖层净风压**：针对墙体和屋顶覆盖层的风压。 本课程的目标是帮助学习者掌握中高层建筑结构构件和覆盖层风压及底部弯矩计算的详尽流程，融合理论知识与实际工程经验。课程提供终身访问权限，学员可免费获取未来的更新内容。
In this course, I will explain the full and detailed process of calculating the wind pressure and base bending moment for a medium height building.The Assessment of Wind Loads for the Design of Structures is based on Australia/New Zealand standard AS1170.2 however the general concept remains the same for every other code. AS1170 has a very detailed and comprehensive process for calculating wind pressures.I often see people get confused with so many paraments and regulations of the code and so I have decided to prepare this course to provide a clear roadmap for anyone who wants to learn the process step by step.My general approach in this course is to explain some basic and general concepts of wind load on structures and then I will explain how to calculate these wind parameters and where in the code I am getting these values from in a real-life example. These parameters include- regional wind speed for different areas of the country,-Terrain/height multiplier and explaining the definition of different train categories,- defining Importance level of the building and return period of the wind considering the occupancy and use of the building- wind direction multiplier,- Hill-shape multiplier,- Shielding multiplier- Site wind speed- Design wind speed- Aerodynamic shape factor for different surfaces or parts of the building.Calculating aerodynamic shape factor requires calculating the external and internal pressure coefficients, area reduction factor, local pressure factor and reduction factor due to parapet, action combination factor, and dynamic response factor for windward wall, Leeward wall, side walls, roof structure, and cladding surfaces of the walls and roof with respect to the two perpendicular directions of the wind.- Net wind pressure for the two perpendicular directions of the wind.- Base moment resulting from the wind pressures for the two perpendicular directions of the wind.- Net wind pressure on claddings which includes wall and roof elements for the two perpendicular directions of the wind.By the end of this course, you will learn about the fundamental and detailed process of calculating the wind pressure and base moment for structural members and claddings of a medium height building.My goal is to add value to my students by conveying my professional/practical experience as well as explaining the theoretical concept behind the design, so please do not hesitate to ask if you ask any questions through the message box here or any other social media links which are provided in our page.Also, you will have lifetime access to the course content which means you will receive all future updates and additions free of charge
