Performance-based design optimization of steel frames, with element sections selected from standard sections, is a computationally intensive task. In this article, an efficient discrete optimization algorithm is proposed for performance-based design optimization of steel frames. The computational efficiency is improved by searching in a sensible manner, guided by the deformation information of structural elements. To include all standard sections in the design space, the cross-sectional area ( Area) and moment of inertia ( Ix) are selected as the design variables. Based on different relationships between Area and Ix, a twofold strategy is put forward, which includes a quick exploration and an elaborate exploitation. For comparison, a similar algorithm is also proposed, using Area as the only design variable. A fixed relationship between Area and other sectional properties is used. Two numerical examples are presented to minimize the structural weight while satisfying performance constraints. The results indicate that the proposed discrete algorithm can achieve lighter structural designs than the area-only algorithm. Furthermore, the convergence history proves that a high computational efficiency can be realized by using the proposed algorithm.

Performance Based Seismic Design

A pushover analysis method based on semirigid connection concept is developed and the colliding bodies optimization algorithm is employed to find optimum seismic design of frame structures. Two numerical examples from the literature are studied. The results of the new algorithm are compared to the conventional design methods to show the power or weakness of the algorithm.

Therapeutic Services

This paper presents strategies for increasing the effectiveness and efficiency of the school-based speech-language pathologist. Various time management strategies are adapted and outlined for three major areas of concern: using time, organizing the work area, and managing paper work. It is suggested that the use of such methods will aid the speech-language pathologist in coping with federal, state, and local regulations while continuing to provide quality therapeutic services.

Perceptions Of School

Purpose School-aged children with hearing loss are best served by a multidisciplinary team of professionals. The purpose of this research was to assess school-based speech-language pathologists' (SLPs) perceptions of their access to, involvement of, and working relationships with educational audiologists in their current work setting. Method An online survey was developed and distributed to school-based SLPs in North Carolina. Results A significant difference in access to and involvement of educational audiologists across the state was found. Conclusions This research contributes to professional knowledge by providing information about current perceptions in the field about interprofessional practice in a school-based setting. Overall, SLPs reported positive feelings about their working relationship with educational audiologists and feel the workload is distributed fairly.
