2、400 ABSTRACT Changing economic conditions, concerns for historic preser- vation, emphasis on fully utilizing conveniently located struc- tures, space shortages, and increasing cost of materials and products used in the construction of new buildings have re- sulted in a need to evaluate and more full
3、y utilize the existing building inventory. To this end, the standard Guideline for Structural Condition Assessment of Existing Buildings (ASCE 77-90) was developed to provide the design community with guidelines for assessing the structural conditions of existing buildings constructed of combination
4、s of material including concrete, masonry, metals, and wood. This edition (SEI/ ASCE 11 -99) replaces ASCE 11 -90. It consists of an overview of preliminary and detailed assessment procedures, of ma- terials properties and test methods, and of evaluation proce- dures for various physical conditions
5、of the structure. The standard is not intended to be inclusive or prescriptive but is expected to serve as a resource document for engineers, owners, and regulatory officials.

17、uideline for Structural Condition Assessment of Existing Buildings is dedicated to the memory of Jerome S. B. Iffland, who passed away in February 1995. Jerry was a founding member of the committee established by ASCE in 1983 and served as its Vice-chairman until his death. While providing overall d
18、irection to the committee based on his extensive professional ex- perience with assessment and rehabilitation of struc- tures, he was an active worker preparing important sections of the standard ready for consensus review. The completion of the 1990 edition of the standard was due in large part to
19、his efforts. Jerry will be especially remembered for drafting parts of this second edition of ASCE 11 while he was very ill. Much of this work was done while he was in the hospital. A special thanks goes to Jerrys wife, Helen, who assisted him in working on the standard during this difficult period.
20、 Committee on Structural Condition Assessment of Existing Buildings dedicates this standard to the memory of Jerry Iffland. He was an inspiration to the committee, setting an example that guided our work even after his death. It is with great pleasure that the ASCE Standards V Changing economic cond
21、itions, concern for his- toric preservation, emphasis on fully utilizing conven- iently located structures, space shortages, and increas- ing cost of materials and products used in the construction of new buildings have resulted in a need to evaluate and more fully utilize the existing build- ing in
22、ventory. Particularly in older cities, emphasis has shifted from replacement to preservation, rehabil- itation, and strengthening of existing buildings. New processes resulting in changes of building systems and business equipment frequently impose greater loads on an existing building structure and
23、 may require additional openings and restructuring. More stringent building code provisions for design load requirements or improved seismic resistance inay also demand retrofitting of structural reinforce- ment. Also, tiny known site conditions should be re- viewed to determine if modifications to
24、structural systems are required. Adaptive reuse, rehabilitation, and improvement of existing buildings all require an accurate assess- ment of present building performance and capability for use by owners, designers, building officials, and contractors. Current data for assessment is dispersed and n
25、ot readily available to many of those making technical decisions. Such information has been com- piled and subjected to a consensus review and ap- proved by this committee to provide the design cominuiiity with a resource standard on building con- dition assessment for selected materials and for oth
26、er areas related to the structural performance of build- ings. To that end, this Standard Guideline for Struc- tural Condition Assessment of Existing Buildings has been prepared for use by qualified professional engi- neers and regulatory officials.
