This book is designed to help the engineer understand the principles of metal form￾ing and to analyze forming problems – both the mechanics of forming processes and how the properties of metals interact with the processes. In this book, an entire chapter is devoted to forming limit diagrams and various aspects of stamping and another to other sheet forming operations. Sheet testing is covered in a separate chapter. Coverage of sheet metal properties has been expanded. Interesting end￾of-chapter notes have been added throughout, as well as references. More than 200 end-of-chapter problems are also included

2.2 Estimating Overall Forces -Vertical dead loads(5～10kN/m²) -Vertical live loads = equivalent dead loads(2～5kN/m²) - Horizontal wind load - Horizontal earthquake load 2.3 Aspect Ratios and Overturn Resistance Aspect ratio (h/d) is one of the main considerations in schematic level. It is very important for overall stability of a building against overturning. 2.4 Strength and Stiffness of Buildings Carrying capacity –enough strength (against loads) Rigidity of building – enough stiffness (against deformation) 2.5 Symmetry and Asymmetry in Building Forms Asymmetry building is caused by: - asymmetry of building elevation - asymmetry of supporting system - asymmetry of dead loads or live loads

Dyspnea is defined as an awareness of difficulty in breathing It is therefore a symptom, usually described by the patient as \shortness of breath,\whether the sensation is due to actual difficulty in breathing or is essentially an awareness of hyperventilation. If the symptom becomes striking, it always companies with dilatation of nares, cyanosis, use of accessory muscles of respiration and abnormalities of respiratory rate, depth or rhythm

24.1 Introduction: the problem of plastic packaging waste Polymers and plastics are typical materials of the last century and have made a tremendous growth of some hundreds of tons/year at the beginning of the 1930s to more than 150 million tons/year at the end of the 20th century with 220 million tons forecast by 2005. Western Europe will account for 19% of that amount. Today
