I I This book is intended to guide practicing structural engineers into more profitable routine designs with the AISC Load and Resistance Factor Design Specification (LRFD) for structural steel buildings. LRFD is a method of proportioning steel structures so that no applica ble limit state is exceeded when the structure is subjected to all appro priate factored load combinations. Strength limit states are related to safety, and concern maximum load carrying capacity, Serviceability limit states are related to performance under service load conditions such as deflections. The term "resistance" includes both strength states and serviceability limit states. LRFD is a new approach to the design of structural steel for buildings. It involves explicit consideration of limit states, multiple load factors and resistance factors, and implicit probabilistic determination of relia bility. The type of factoring used by LRFD differs from the allowable stress design of Chapters A through M of the 1989 Ninth Edition of the AISC Specifications for Allowable Stress Design, where only the resistance is divided by a factor of safety to obtain an allowable stress, and from the plastic design provisions of Chapter N, where the loads are multi plied by a common load factor of 1.7 for gravity loads and 1.3 for gravity loads acting with wind or seismic loads. LRFD offers the structural engineer greater flexibility, rationality, and economy than the previous 1989 Ninth Edition of the AISC Specifications for Allowable Stress Design."

Examines the remarkable career of leading soprano castrato Venanzio Rauzzini (1746-1810), the first castrato to make Britain his home. Venanzio Rauzzini (1746-1810), the celebrated Italian castrato, is best known for his performance in Mozart's Lucio Silla in 1772, with which Mozart was so pleased that he composed for the singer the famous motet Exsultate Jubilate. In 1774, Rauzzini moved to London where he performed three seasons of serious operas at the King's Theatre. From 1777 until his death in 1810, he was the director of the concert series in Bath, a series that matched the prestige of any that were given in London. In addition, he composed prolifically, writing music for eleven operas. This book is a study of Rauzzini's remarkable yet often overlooked career in Britain. Paul Rice chronicles Rauzzini's performances at the King's Theatre and examines his leadership of the Bath subscription concerts from 1780-1810, recovering much of the repertory. Rice shows in detail how Rauzzini responded musically to the social and political conditions of his adopted country, and analyzes the castrato's reception, as well as compositional choices, shedding new light on changing musical tastes in late eighteenth-century Britain. Paul F. Rice is Professor of Musicology at the School of Music, Memorial University of Newfoundland.
