Book Description
Analysis of the construction load distribution during construction of multistory concrete buildings is critical for both construction safety and economy. Recent reduction of load factors used in design of the permanent structure has resulted in less strength availability in the construction stage and need for tools to better support shoring and reshoring analysis. Using the traditional simplified method to analyze loads in a concrete structure under construction, spreadsheet models have been developed which distribute load inputs chosen by the engineer. The models determine the vertical loads resisted by the following shoring systems: one set of shores with either two or three sets of reshores; two sets of shores with either one or two sets of reshores; or three sets of mechanical drophead shores. Analysis can be performed using either unfactored or factored loads and using either actual uniform loads or loads expressed as a proportion of slab dead load, D. Slab liftoff was then analyzed to prevent improper loading conditions during the construction cycle of multistory concrete buildings. The results of the models were validated by comparison with previously published shoring analysis. Lastly, a sensitivity analysis is performed to compare the loads supported by individual slabs and sets of shores in each model during the placement of upper floors.

Book Description
The most critical state of a structure's lifetime is during construction; many more disasters occur during construction than after projects have been completed. This book helps readers to determine construction loads; understand performance criteria during construction; prevent construction delays; maintain structural strength and stability; find relevant codes and standards; learn methods of shoring, reshoring, bracing and guying, and completing other temporary work; spot potential hazards; eliminate construction-created structural disaster; and maximize site safety. The book also covers concrete frame analysis and provides comprehensive treatment of topics such as construction procedures and shoring scheduling. Concrete Buildings: Analysis for Safe Construction also features a diskette that contains the computer program, SHORING2, a menu-driven, user-friendly program capable of calculating the loads imposed on shores, reshores, and slabs at every state of construction on high-rise reinforced concrete buildings. The program can also assess safety at each stage of construction. Concrete Buildings: Analysis for Safe Construction's "back to basics" approach, realistic detailed worked examples, and emphasis on safety through the use of computer programs, will benefit structural engineers, contractors, inspectors, construction managers, building officials, and construction safety specialists. The book is an important guide for safe analysis of concrete buildings during construction.
