Course Aim: To teach structural configurations, modeling techniques and analysis of high-rise buildings.

Intended Learning Outcomes:

On successful completion of the course, the students should be able to;

➢    select structural configurations for vertical and lateral load resistance systems of high-rise buildings.

➢    discuss design philosophy for high-rise buildings.

➢   evaluate the behaviour of high-rise buildings against wind and earthquake actions.

➢    analyze high-rise buildings and design structural components.

Course Content:

➢    Introduction to high-rise building: What is “High-Rise building”?, Different lateral load resistance systems of High-Rise building (Moment resisting frame, Shear wall-frame coupled, Braced frame, Tubular structure, Braced tube systems, Unique-Innovative systems), Review of vertical load resisting system of High-Rise building, Function of service core, Required professional skills, Building services applicable to high-rise buildings.

➢    Design process and philosophy: Structural design considerations and process (Story drift for occupant perception, Stability and overturning, Axial shortening of columns, Transfer girders and deep beams, Shear wall design and detailing, Construction sequence analysis, Design for lateral load, Design of Cladding), Overall design process, Design philosophy and process, Consideration of safety, Philosophies in current use, Selection of structural system, Typical characteristics of residential buildings and commercial buildings, The building structural system (Physical and Conceptual)

➢    Analysis and design for lateral loads: Approximate analysis methods for lateral loads, Wind and earthquake effects on high rise buildings, Analysis and design of high-rise building for wind and earthquake loading conforming to a standard code of practice

➢   Applications of general-purpose finite element programs for analysis and design of high-rise building: Development of finite element model, Modal analysis, Gravity load analysis and design, Lateral load analysis and design (For code based equivalent wind and earthquake loads), Construction sequence analysis.
