Abstract:

Essential steps in modifying structures for the purpose of adapting old buildings to new use are discussed in this paper. Eight basic steps are described: (1) pre-liminary site visit, (2) documentation of original design and construction, (3) identification of desired changes in the building, (4) identification of code requirements applicable to building alterations, (5) development of structural modi-fication schemes and preliminary cost estimates, (6) verifi-cation of "as is" condition, review of adequacy of proposed modification scheme and estimated cost, (7) completion of design and construction documents, including drawings and specifications, and (8)'coordination of engineering design with construction quality control and accommodation of possible need for design changes during construction.

Abstract:

This paper describes nondestructive evaluation (NDE) methods that can be used in assessing the condition of concrete and masonry materials and components in structures being rehabilitated or preserved. Metal reinforcement is also included. The appropriate use of NDE methods is discussed and a recommended approach to selecting NDE methods for specific situations is given. NDE methods are briefly described based on their principle of operation, information they provide, applications, expertise required to use them, and advantages and limitation to their use.

Abstract:

This paper describes the engineering procedures in the renovation of Kresge Auditorium which is located at the Massachusetts Institute of Technology in Boston. Described are inspection procedures used to determine any structural deterioration which may have occured since the building's inception. These procedures included visual inspection to determine cracking and other aspects which would possibly reduce the structure strength, pulse-echo test and chemical and petrographic tests of the structure's concrete as well as continuous monitoring of structure motions during remedial construction. To assist in this remedial work, a series of finite element analyses were performed to determine stress levels within the structure. These analyses considered initial construction stresses as well as increased stresses due to structure deterioration. Based on the above, a series of structural modifications were developed and implemented in the structure restoration.

Abstract:

This paper discusses the investigation, renovation, and restoration of ancient masonry as well as the design of modern reinforced brick masonry structures. Two categories (a) ancient brick and stone masonry structures and (b) modern reinforced brick masonry structures are discussed. Relationship between modern shell theory formulas are derived. A practical procedure which has been used for constructing modern reinforced brick structures is outlined for category (b) structures. Case studies are discussed for category (a) structures for ancient buildings such as the Soltanieh Mosque being restored by ISMEO, and the Golestan Palace which has been redesigned and restored under the supervision of the author, applying the shell theory as presented in this paper. The paper also contains case studies for two categories, (b) modern buildings "Iran Center for Management Studies" in conjuction with Harvard University and the "Bu Ali Sina University," which are designed in accordance with the criteria mentioned above for the design of modern reinforced brick masonry structures.

Abstract:

This paper provides an overview of building regulations applied to rehabilitation. Covered are constraints due to regula-tion, technical activities to improve regulations, and research needed to effectively use the existing building stock. Progress has recently been made toward removal of regulatory constraints. Many technical problems remain to be solved through research which needs support from both the public and private sectors. The analysis of numerous studies indicates a strong need for technical evaluation techniques to assist decision making for building rehabilitation.
