the current study focuses on the experimental investigation of frp strengthening of rc portal frame subjected to combined vertical and horizontal loads. the main target of this research is to enhance the proposed structural properties that the rc portal frame had before the seismic occurrences by providing retrofitting of both columns and joints with more deformation capacity. the effect of var...

In this paper we report employing frame-based system as the basis to build up a ontology-based portal. The basic idea is to transform the ontology schema and instances collected from various digital library sites using the semantics of the frame-based system. The service programs written using the frame-based reasoning formalism thus can make use the knowledge.
