Abstract
In a knee brace system, at least one end of the diagonal member is connected to a small knee element instead of being connected to the beam-column intersection. The ductility in a knee bracing frame (KBF) is due to the knee element yielding in shear. On the other hand, the required lateral stiffness in such frames is provided by a diagonal member. Yielding of the knee element during a strong earthquake would ensure overall system stability without damaging the main structural components. Thus, reconstruction of the earthquake-resistant system would be easier and more economic. Considering the increased ductility and energy damping requirements set forth for building structures in seismic zones, the authors studied in the paper the effects of the length and properties of the materials used in knee bracing systems. To obtain reliable modeling and analysis results, first a suitable sample was selected from among the credible test models used in world renowned research centers and, subsequently, this sample was modeled by ANSYS software. Then, modeling accuracy was established by comparing corresponding load-deformation curves. Finally, by varying the knee member length and material properties, numerous models were generated in the ANSYS environment. Ultimately, such characteristics as ductility, behavior coefficient, ultimate strength, energy absorption, etc. were calculated and the relevant tables and curves produced


Keywords: Knee brace, knee member/element, materials properties, ductility, behavior coefficient, nonlinear static analysis.

The long-term success of periodontal therapy is dependent on proper diagnosis and removal of subgingival tooth-borne accretions in the form of calculus and bacteria. From a clinical perspective, better visualization during the diagnostic and therapeutic phases has been shown to yield better results compared to traditional approaches. Minimally Invasive Periodontal Therapy evaluates the advantages of using minimal invasive techniques, the technologies available for enhancing visualization during minimally invasive therapy, and step-by-step illustrates the clinical use of each technique. Each chapter addresses the advantages and disadvantages of minimally invasive therapies, rationale for the approach, and the advantages and limitations of each of the current methods of improving visualization. The chapters then provide an evidence-based review of the technologies and procedures, and end with case studies for each visualization procedure, featuring clinical photographs
