Abstract

Earthquake-resisting frame systems that are designed based on current seismic provisions provide life safety performance in a large earthquake, but may have significant structural damage or residual drift due to energy dissipation in designated structural members. The damage leads to difficult or expensive repairs after a large earthquake. Therefore, development of a structural system that has both energy dissipation and self-centering properties in earthquakes is needed to improve seismic performances of buildings. This paper presents a viable solution that was validated by multiple cyclic tests of an innovative brace, called a dual-core self-centering sandwiched buckling-restrained brace (SC-SBRB). The proposed brace combines the self-centering property of a dual-core self-centering brace (DC-SCB) and the energy dissipation of a sandwiched buckling-restrained brace (SBRB) together. The dual-core SC-SBRB is essentially a DC-SCB that is positioned concentrically with a SBRB to create both the self-centering and energy dissipation properties in either tension or compression. A 7860 mm-long dual-core SC-SBRB, which uses ASTM A572 Gr. 50 steel as bracing members and ASTM A416 Grade 270 steel tendons as tensioning elements, was cyclically tested six times to validate its kinematics and cyclic performance. The test program demonstrated that the proposed dual-core SC-SBRB provides stable hysteretic responses with appreciable energy dissipation, self-centering behavior and large deformation capacity before low-cycle fatigue failure of the SBRB core.

Design And Development Of Medical Electronic Instrumentation by DAVID PRUTCHI and MICHAEL NORRIS

//

The medical devices industry is booming. Growth in the industry has not stopped despite
globally fluctuating economies. The main reason for this success is probably the self-sus-
taining nature of health care. In essence, the same technology that makes it possible for
people to live longer engenders the need for more health-care technologies to enhance the
quality of an extended lifetime. It comes as no surprise, then, that the demand for trained
medical-device designers has increased tremendously over the past few years. Unfortu-
nately, college courses and textbooks most often provide only a cursory view of the tech-
nology behind medical instrumentation. This book supplements the existing literature by
providing background and examples of how medical instrumentation is actually designed
and tested. Rather than delve into deep theoretical considerations, the book will walk you
through the various practical aspects of implementing medical devices.
