课程概况

房屋为我们遮风避雨,让我们安心工作、生活,而结构系统又是房屋的骨干,让房屋能站的又高、又直、又稳。你知道横者为梁,直者为柱,但你知道在结构工程师的眼中,梁与柱有什么其他的不同吗?他们其中藏著什么秘密,能支撑起整个结构?工程师要怎么决定梁该有多深?柱该有多粗?该用矩形、圆形还是其他形状?该用实心还是空心?在有地震的地方,设计上是否又有不一样的考量?

材料力学是通往上述问题解答关键的一步。在材料力学(一)裡,我们会由大家熟知的虎克定律开始,以盖房子的重要材料「结构钢」为例,深入探讨「力量」与「变形」这两个令结构工程师爱恨交加的物理量之间的关系。然后依序探讨结构杆件受轴力(拉/压)、受扭、受弯、受剪四大外力作用下,会在杆件内部产生怎样的相对应变形与受力,并探讨建筑结构设计概念与提供杆件设计演算范例。

本课程是希望精通「钢筋混凝土设计」、「钢结构设计」、「木构造设计」者必备的先修课程,也为对「弹性力学」有兴趣者,提供许多基础知识与这些知识如何实际应用于工程设计。主要授课对象为土木、建筑相关从业人员与在学学生,其他包括工学院各科系同学或对材料力学有兴趣的人士,也欢迎选修。

常见问题解答

我能够在注册和支付前预览课程内容吗?
You can preview a selection of the course content (usually the first week’s lectures) by selecting the “Preview Course” option. Once you enroll and purchase the course, you’ll have access to all content once the session begins (for session-based course) or immediately (for self-paced courses). If you choose to explore the course without purchasing, you may not be able to access certain assignments.

我什么时候能够访问课程视频和作业?
Once you enroll and purchase the course, you’ll have access to all content once the session begins (for session-based course) or immediately (for self-paced courses); if you choose to explore the course without purchasing, you may not be able to access certain assignments. You can watch the lectures and submit the assignments at any time that works for you, although you should try to keep up with the suggested deadlines to stay on track.

如果我需要额外的时间来完成课程会怎么样?
Not a problem – course schedules are flexible, and course fee payments provide 180 days of full course access and Certificate eligibility. Self-paced courses have suggested deadlines, but you won’t be penalized for missing deadlines as long as you earn your Certificate within 180 days. Session-based courses may require you to meet deadlines to stay on track; but if you fall behind, you can switch to a later session, and any work you’ve completed will transfer with you.

我支付此课程之后会得到什么?
If you pay for this course, you will have access to all of the features and content you need to earn a Course Certificate. If you complete the course successfully, your electronic Certificate will be added to your Accomplishments page – from there, you can print your Certificate or add it to your LinkedIn profile. Note that the Course Certificate does not represent official academic credit from the partner institution offering the course.

我能够免费学习此课程吗?
You can access video lectures and certain assignments for free in all courses. The free experience is intended to give you the opportunity to explore the course and decide if it is something you wish to pursue. If you do decide that you would like to complete the course, we encourage you to upgrade your experience by purchasing the course, or to apply for financial aid if you cannot afford the course fee.

退款条例是如何规定的?
You will be eligible for a full refund until two weeks after your payment date, or (for courses that have just launched) until two weeks after the first session of the course begins, whichever is later. You cannot receive a refund once you’ve earned a Course Certificate, even if you complete the course within the two-week refund period. View our full refund policy.

有助学金吗?
Yes! Coursera provides financial aid to learners who would like to complete a course but cannot afford the course fee. To apply for aid, select “Learn more and apply” in the Financial Aid section below the “Enroll” button. You’ll be prompted to complete a simple application; no other paperwork is required.
