This book brings together the author's insights, ideas, lecture notes, exam materials, through 31 years of experience in teaching, consulting, and supervising design and construction projects. Its primary aim is to guide readers in designing safe and cost-effective structures. The book includes numerical examples in both SI and US customary units, helping students grasp the design process for structural components, including irregularly shaped beams, columns, and slabs, in a clear and accessible manner. It also covers the design of shear walls and basement walls, as well as considerations for lateral and dynamic loads, such as those from earthquakes and blasts.
