课程简介

Coursera在线课程“钢框架仓库的风荷载设计 - 第1部分”概述: 本课程将详细讲解钢结构仓库的墙体和屋顶的结构构件及围护结构的风压设计计算全过程。课程参考澳大利亚/新西兰标准AS1170.2,并强调其基本概念适用于其他规范。 **第一部分内容涵盖:** * **风荷载基础和概念:** 结合实例讲解风荷载作用于结构的基本原理。 * **风参数计算:** 详细说明如何根据AS1170.2计算各项风参数,包括: * 区域风速(不同地区) * 地形/高度系数(不同地形类别定义) * 建筑重要性等级及考虑建筑使用情况的回报周期 * 风向系数 * 山形系数 * 遮挡系数 * 场地风速 * 设计风速 * **气动形状系数 (Aerodynamic Shape Factor):** 讲解计算外压和内压系数、面积折减系数、局部风压系数、作用组合系数、渗透性围护结构系数、动态响应系数等,这些系数需针对结构迎风面、背风面、侧面、屋顶结构及墙面和屋顶的围护结构,并考虑结构沿四个主要轴向的风作用。 * **结构构件设计风压:** 计算仓库不同门式框架沿四个主要轴向作用在墙体和屋顶结构构件上的设计风压。 * **摩擦阻力:** 计算屋顶和侧墙的摩擦阻力。 * **风压变化:** 分析风压沿屋顶和长墙的变化规律。 **课程目标:** 通过完成本课程(含第二部分),学员将全面掌握钢框架仓库的结构构件和围护结构风压计算的详细过程。讲师旨在结合理论知识和实际经验,为学生提供学习价值,并鼓励学生提问。课程内容提供终身访问权限,并包含未来所有更新。

In this course, I will explain the full and detailed process of calculating the design wind pressures for structural members and cladding surfaces of the walls and roof of a steel-framed warehouse.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.There are so many parameters and requirements in the code which often leaves people with some confusion and question marks on how to approach these. so I have decided to prepare this course to provide a clear roadmap for anyone who wants to learn the process step by step.This course, "Design Wind Pressures on a Steel Structure Warehouse" includes two parts:Please make sure to watch both parts to learn the whole design process.In the first part of this course, you will learnabout the basics and general concepts of wind loading on structures within our practical and real-life example and also I will explain about how to calculate the wind parameters and where in the code I am getting these values from. 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 buildings 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, action combination factor, permeable cladding factor, and dynamic response factor.These factors have to be determined for windward walls, Leeward walls, sidewalls, roof structure, and cladding surfaces of the walls and roof with respect to wind on 4 major axes of the structure.- Design wind pressure on structural elements of the walls and roof for different portal frames of this warehouse for the 4 major axes of the structure.- Frictional Drag forces on Roof and Side Walls.- How wind pressure changes along the roof and long walls.In part 2, I will explain:- Design wind pressure on doors and windows and how the size of the opening can impact the net wind pressure on wall and roof surfaces.- Design wind pressure on wall claddings and supporting structures and how to calculate localized wind pressures on walls claddings- Design wind pressure on roof claddings and supporting structures and how to calculate localized wind pressures on roof claddings.- Evaluating the impact of the big openings on internal and net wind pressure on cladding surfaces of the roof and walls.- How wind pressure changes along the roof and long walls.- Summary of the net wind pressure on different areas of the roof.By the end of these two courses, you will learn about the fundamental and full and detailed process of calculating the wind pressure for structural members and claddings surfaces of the walls and roof of a steel-framed warehouse.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.
