Abstract: In this paper, weak axis connections with steel moment frames were evaluated seismic performance. Weak axis connections with proposed prequalified connections in US and weak axis column-tree type connections were tested. As a results, weak axis prequalified connections were evaluated lower ductile than weak axis column-tree type. Prequalified connections satisfied ordinary moment frame, while column-tree type connections met the special moment frame condition.

Abstract: The current research is directed towards studying the creep compliance characteristics of asphalt concrete mixtures modified with cement dust. This study can aid in assessing the permanent deformation potential of asphalt concrete mixtures. Cement dust was added to the mixture as mineral filler and compared with regular lime stone filler. A power law model was used to characterize the creep compliance behavior of the studied mixtures. Creep testing results have revealed that the creep compliance power law parameters have a strong relationship with mixture type. Testing results of the studied mixtures, as indicated by the creep compliance parameters revealed an enhancement in the creep resistance, Marshall stability, indirect tensile strength and compressive strength for cement dust mixtures as compared to mixtures with traditional lime stone filler.
