This book aims at detailed analysis and structural design of high rise buildings with real life examples. The knowledge of the design of high building for gravity and seismic loading is highly essential for the upcoming engineers to work in actual field efficiently. The various structural analysis and design aspect for high rise buildings are taught in the undergraduate level but not in full depth. Therefore the objective of this book is to understand the analysis and design of high rise building for gravity and seismic analysis. Since the designing for gravity and seismic is usual in actual field but retrofitting of high rise building is less common but it is highly important to study. In this report retrofitting techniques are also proposed for high rise building taking into account of the gravity and seismic loads. The understanding of current softwares for design is the need of the hour especially for the design structural engineers. Therefore, ETABS was used for the analysis of gravity and for earthquake loads. The gravity analysis and design is based on ACI-99 and earthquake analysis is based on UBi97.

With the passage of time and advancement in technology, people headed to cities from villages in pursuit of better occupations and luxurious lifestyles. As the cities ran out of space, it became problematic to accommodate the ever- increasing population. In this time of dilemma, civil engineers rose to the occasion and faced the challenge of providing accommodation to a large number of citizens in a limited space, defiantly. Hence, the proposal of high-rise buildings was put forward. Some decades back, there were no softwares to carry out the analysis and design of high-rise buildings. With the progress of time, as computer softwares were developed, a new era of civil engineering dawned, which made it possible to analyze and design high-rise buildings. High-rise buildings are, however, susceptible to earthquakes. In addition, the effect of wind load also becomes more & more prominent with the increase in height of a structure. Therefore, precise analysis & design of such a structure should be carried out in order to avoid any future catastrophe which is the objective of writing this book.

This book proposes a new concept in corrosion modeling approach which is based on the existing scientific corrosion laws and is also verified by experimentation. An enhanced simulation tool has been developed for the coupled effects of mass and energy transport through porous media of reinforced concrete using cutting edge corrosion modeling techniques. A comprehensive enhancement of finite element model for predicting the rate of steel corrosion in concrete structures under the effect of various environmental actions is developed. Deep investigations were conducted for the effects of various environmental actions namely, chloride, temperature, oxygen, carbonation and moisture on corrosion of reinforcing steel in concrete through extensive experimentation and the environment variables that have been overlooked in the past research works were further explored and understood properly.

This book details the analysis and design of high rise buildings for gravity and seismic analysis. It provides the knowledge structural engineers need to retrofit existing structures in order to meet safety requirements and better prevent potential damage from such disasters as earthquakes and fires. Coverage includes actual case studies of existing buildings, reviews of current knowledge for damages and their mitigation, protective design technologies, and analytical and computational techniques. This monograph also provides an experimental investigation on the properties of fiber reinforced concrete that consists of natural fibres like coconut coir and also steel fibres that are used for comparison in both Normal Strength Concrete (NSC) and High Strength Concrete (HSC). In addition, the authors examine the use of various repair techniques for damaged high rise buildings. The book will help upcoming structural design engineers learn the computer aided analysis and design of real existing high rise buildings by using ACI code for application of the gravity loads, UBC- 97 for seismic analysis and retrofitting analysis by computer models. It will be of immense use to the student community, academicians, consultants and practicing professional engineers and scientists involved in the planning, design, execution, inspection and supervision for the proper retrofitting of buildings.
