At present, reducing subgrade settlement of soft soil foundation is a key problem in high-speed railway construction. Pile-slab structure is a widely-utilized form of foundation structure to reduce the subgrade settlement in China. In order to save the engineering cost for high-speed railway construction in developing countries, the author developed a pile-slab structure and named it as the new...

Among forest management methods, selection cutting puts into practice applications that follow the processes naturally occur in ecosystem. The purpose of this research was to investigate effects on stand structural characteristics and growth form trees. effect evaluated terms frequency standing volume trees deadwood, diversity tree species indices, complexity index (SCI), height-to-diameter rat...

Abstract M oment R esisting (MR) einforced C oncrete (RC) frame system presented in the current seismic design standards and required to on-site action develops soft storey mechanisms. In practice, idealized theorized ductile response specified for this structural type does not occur. these conditions, research study presents a logical scheme regarding development method of MR RC system. The ma...

Saying goodbye to the old and ready for the challenges of the new, RCN President Maude Storey delivers a special New Year message to the College membership.

torsion of many symmetric structures, which were designed based on the seismic codes, is due to their asymmetricity induced during inelastic behavior. although the structure was designed symmetrically assuming elastic based criteria, different factors such as material inconsistency in structure, construction details discrepancy and construction errors may result in asymmetric behavior in inelas...
