Continuous professors' teaching quality evaluation has a great effect on their teaching quality progress. How to do an evaluation and criteria that are used to it, are really important. In this research, common methods for evaluating teaching quality are studied and new criteria were suggested. This research tries to select the statistical population among the engineering field and uses the students and professors’ idea to recognize the teaching evaluation criteria in theoretical lessons as well as project, laboratory and workshop lesson and come to new conclusions. In introducing the new criteria indexes including lessons plan, professional behavior, test questions, social behavior, case studies of the postgraduate and professors' performances in workshop and laboratory lessons and students' projects and thesis are targeted. For identifying criteria of professors' teaching performance evaluation, the research was a kind of descriptive-survey one. In this research, a statistic population including 340 students and 106 professors were selected as a sample group and their opinions about the criteria for evaluating the professors' teaching quality were collected. Data was analyzed by SPSS version 16.0 software. The professors and students’ opinions were processed by using this software. The results indicate that for professors, criteria for lesson plan, scheduling in class session by following the book topics and for students, providing booklet, answering questions, using suitable examples, professor skill in experimental lesson, participation and supervision of projects and student’s thesis are the most important criteria for evaluating professors' teaching quality.

Performance design based on performance is a new method in which structural damage against different levels of risk (earthquake) is clearly assessed and structural and non-structural performance of structures by limiting strength, stiffness and ductility. Members are controlled. To achieve these goals, a nonlinear analysis of the structural model is essential. To perform this analysis, the basic characteristics of the structure (initial strength and stiffness) are required. The closer the initial values are to the final values, the easier and faster the process of analyzing and designing the structure will be. The main purpose of this paper is to provide a method that can be used to easily and quickly obtain the initial strength and stiffness of the structure for nonlinear analysis. For this purpose, coefficients are proposed that can be used to make the required strength and stiffness of reinforced concrete bending frames for each of the functional modes; Intermediate use (IO), life safety (LS) and structural destruction limit (CP) were determined. These coefficients are the coefficient of behavior (Rw) and the coefficient of magnification of the displacement (Cd), which are used to calculate the strength and stiffness required by the structure, respectively. The recommended values for behavioral coefficients in different functional states of IO, LS, and CP are 2.28, 4.43, and 5.3, respectively. The values of 2.29, 4.73 and 5.83 have also been suggested for displacement magnification coefficients in different functional modes. Studies show that the use of the above coefficients in calculating the required strength (base shear) and initial stiffness (by controlling lateral displacement) of structures, will make the next steps of work and nonlinear analysis of structures easier and faster. .
