Description
This subject introduces students to the concepts and techniques of structural dynamics and their applications in the design and analysis of civil structures affected by dynamical loading such as earthquakes, strong winds and operational dynamic loads. In completion of the subject, students are expected to develop: (i) an understanding of the nature of dynamic (time varying) loads, with particular emphasis on earthquake loads and influence of such loads on the behaviours of the structures, (ii) the ability to assess the response of civil engineering structures to such loads, taking into account load-structure interaction, (iii) structural design approaches satisfying both strength and serviceability requirements of Australian Standards, and (iv) concepts and practices in mitigating the hazards due to such loads or utilising some effects of these loads to assess conditions of the structures.
Subject learning objectives (SLOs)
Upon successful completion of this subject students should be able to:
| 1. | Understand structural dynamics and earthquake concepts and techniques in relation to its applications in the design and analysis of civil structures. (D.1) |
|---|---|
| 2. | Apply structural design approaches incorporating structural dynamics satisfying both strength and serviceability requirements of Australian Standards. (C.1) |
| 3. | Communicate structural dynamics and earthquake design, including concepts and approaches to stakeholders. (E.1) |
Course intended learning outcomes (CILOs)
This subject also contributes specifically to the development of the following Course Intended Learning Outcomes (CILOs):
- Design Oriented: FEIT graduates apply problem solving, design thinking and decision-making methodologies in new contexts or to novel problems, to explore, test, analyse and synthesise complex ideas, theories or concepts. (C.1)
- Technically Proficient: FEIT graduates apply theoretical, conceptual, software and physical tools and advanced discipline knowledge to research, evaluate and predict future performance of systems characterised by complexity. (D.1)
- Collaborative and Communicative: FEIT graduates work as an effective member or leader of diverse teams, communicating effectively and operating autonomously within cross-disciplinary and cross-cultural contexts in the workplace. (E.1)
Contribution to the development of graduate attributes
Engineers Australia Stage 1 Competencies
This subject contributes to the development of the following Engineers Australia Stage 1 Competencies:
- 1.3. In-depth understanding of specialist bodies of knowledge within the engineering discipline.
- 2.1. Application of established engineering methods to complex engineering problem solving.
- 2.2. Fluent application of engineering techniques, tools and resources.
- 2.4. Application of systematic approaches to the conduct and management of engineering projects.
- 3.2. Effective oral and written communication in professional and lay domains.
Teaching and learning strategies
The delivery of the subject will include:
- Lectures and tutorials sessions: the subject is designed to have face-to-face / on-campus delivery with highly interactive features, coupled with plenty of online materials on state-of-the-art technology for flipped class learning.
- Computer- and physical- laboratory sessions: these hand-on sessions, as above, will be delivered online via Zoom. As they have been designed to develop understanding on difficult concepts and foster problem solving skills, the subject will try to use online technology to maintain its feature. Through a real-time streaming of video and data, the subject will create a new laboratory experience for studnets using UTS state-of-the-art shaker table facility and ancillary equipment, to integrate the acquired knowledge and apply it to a simple structure. Laboratory sessions will also enhance student’s understanding of certain principles and demonstrate some practical aspects of the field of structural dynamics
- A group project and an individual project: These learning components have been designed to help students for mastering the subject on deepening the understanding, developing problem solving skills, assisting integration of learnt knowledge and practice, as well as encouraging students’ active self-learning. There will be bonus marks given to the projects (in relation to the reports, learning portfolio and the interview) to encourage team working, deeper learning and innovations.
