This book focuses on the revisions to the seismic load requirements set forth in the latest edition of the Standard for minimum design loads. Mirroring the organization of the seismic chapters in ASCE 7-10, this handy reference briefly summarizes each change to the seismic provisions that might affect actual practice or enforcement and immediately follows up with the precise wording of the change. The impact of each update is explained in clear, straightforward language accompanied by diagrams, examples, and color photographs and illustrations to enrich the reader's understanding.Content:Front Matter Preface Table of ContentsPart I.
