As a combination of mathematical and statistical techniques, response surface （RS） methodology has been successfully applied to design optimization, response prediction and model validation. With the aid of RS methodology, these two serial papers present a finite element （FE） model updating and validation method for bridge structures based on structural health monitoring. The key issues to implement such a model updating are discussed in this paper, such as design of experiment, parameter screening, construction of high-order polynomial response surface model, optimization methods and precision inspection of RS model. The proposed procedure is illustrated by a prestressed concrete continuous rigid-frame bridge monitored under operational conditions. The results from the updated FE model have been compared with those obtained from online health monitoring system. The real application to a full-size bridge has demonstrated that the FE model updating process is efficient and convenient. The updated FE model can relatively reflect the actual condition of Xiabaishi Bridge in the design space of parameters and can be further applied to FE model validation and damage identification.展开更多

The aim of this study is to investigate the family variables, including domicile, parents＇ education, their age, the type of work they do, family size, and family income. As to the social responsibility＇s dimensions for sample selected for this study; hence, it includes personal, ethical, national, environmental, health, and social responsibility. The current study adopted the descriptive approach along with a demographic data form and the social responsibility＇s scale. The sample selected consisted of 330 female students from various colleges within King Abdulaziz University. The results indicated that there was an impact on all the variables, thus such impact was in favor of those living in rural areas as to the ethical dimension and in favor of urban people as to the dimensions of accountability, parents＇ level of education, parents＇ seniority, working mothers, greater family size, and higher income.展开更多
