ST4003 Wind and Cyclone Effects on Structures Syllabus:
ST4003 Wind and Cyclone Effects on Structures Syllabus – Anna University PG Syllabus Regulation 2021
OBJECTIVE:
To study the concept of wind and cyclone effects for the analysis and design of structures.
UNIT I INTRODUCTION
Introduction, Types of wind – Characteristics of wind – Method of Measurement of wind velocity, variation of wind speed with height, shape factor, aspect ratio, drag and lift effects – Dynamic nature of wind –Pressure and suctions – Spectral studies, Gust factor.
UNIT II EFFECT OF WIND ON STRUCTURES
Classification of structures – Rigid and Flexible – Effect of wind on structures –Vortex shedding, translational vibration of structures – Static and dynamic effects on Tall buildings – Chimneys
UNIT III DESIGN OF SPECIAL STRUCTURES
Design of Structures for wind loading – as per IS, ASCE and NBC code provisions – Design of Industrial Structures– Tall Buildings – Chimneys – Transmission towers and steel monopoles
UNIT IV CYCLONE EFFECTS
Cyclone effect on – low rise structures – sloped roof structures – Tall buildings. Effect of cyclone on claddings – design of cladding – use of code provisions in cladding design – Analytical procedure and modeling of cladding.
UNIT V WIND TUNNEL STUDIES
Wind Tunnel Studies, Types of wind tunnels, Types of wind tunnel models – Modelling requirements – Aero dynamic and Aero-elastic models, Prediction of acceleration – Load combination factors – Wind tunnel data analysis – Calculation of Period and damping value for wind design
OUTCOMES:
On completion of the course, the student is expected to be able to
CO1 Explain the characteristics of wind
CO2 Evaluate the intensity of wind on structures
CO3 Design some special structures subjected to wind loading
CO4 Design of structures for cyclone
CO5 Model and analyse a structure in a wind tunnel
