Preface
This book presents group of examples on the design of reinforced concrete
members according to ACI318-14 and utilizing the design aids of ACI SP-17(09):
ACI Design Handbook. The examples are given in metric units. Generally, each
chapter starts with extracts from the ACI318-14.
The book is useful for Structural Engineering students and practicing
engineers. It provides day to day design examples and consists of eleven chapters
which cover beams, slabs, columns, footings, water side sections, deflection and
prestressed concrete. In addition to the considered design for vertical loads, the book
includes the design for seismic loads.
