Course Overview
This course covers the fundamentals of multi-storey building design with a focus on earthquake and gravity loading, building response, design of lateral-load resisting systems and design of the gravity load resisting systems. The course will provide an understanding of the design of different structural systems including steel moment frames, eccentrically braced frames, reinforced concrete frames and reinforced concrete walls. This will include ductile seismic design, capacity design principles and the importance of second order effects on the inelastic response of structures. It is intended to provide students with a comprehensive overview of the concepts and philosophy behind the performance and design of multi-storey buildings, covering both lateral loading and gravity loading systems.
The first module will cover general seismic analysis and design, application of NZS 1170.5 (the 2016 version) and dynamic response of multi-storey buildings, including the fundamentals of the three different analysis methods; equivalent static, modal response spectrum and numerical integration time history. This module is intended to complement the introductory module of STRCTENG 710 Low Rise Structures Design in terms of seismic loading principles, structural systems, and load paths. The concept of capacity design and its application to the seismic design of structures will be introduced. This will cover both the seismic resisting system and the gravity load carrying system.
The second module will cover the design of reinforced concrete structural systems and the third module the design of steel structural systems. These modules will present the design methods for common structural systems used in multi-storey buildings, including determining critical design actions, component design provisions, and seismic detailing requirements. The course will present the fundamental theory as well as the application of this when following New Zealand structural design standards. Assignments will allow for key parts of the design process to be implemented for example multi-storey buildings using reinforced concrete and structural steel as the lateral load resisting system and supporting structure for the floor system.
Course Philosophy
The object of this course is to give the students an understanding of the concepts involved in the design of multi-storey building systems. The emphasis is on developing an understanding of fundamental behaviour, so that the application of the requirements of the loadings and materials standards can be understood. The principal focus will be on reinforced concrete systems (frames and walls) and structural steel systems (frames and braced frames). It also teaches preliminary design procedures for multi-storey buildings, giving students an understanding of the concepts and preliminary design requirements. The assignments will build on the material covered in previous structural mechanics and design courses, especially STRCTENG 302 and STRCTENG 303.
