Semiflexible polymers subject to hydrodynamic forcing play an important role in cytoskeletal motions in the cell, particularly when filaments guide molecular motors whose motions create flows. Near hyperbolic stagnation points, filaments experience a competition between bending elasticity and tension and are predicted to display suppressed thermal fluctuations in the extensional regime and a bu...

the basic strategy of reduce the ductility demand and related concentrated tensions at moment resistance connections is reduce the section of the beam at connected region to column. by this method plastic hinge done at the reduced cross section and this local reduction decreases the demand of the components of connection. on this basis, in present study a new beam-to-column moment connection wi...

In this work, the behavior of reinforced concrete columns under biaxial bending is studied. This work aims at studying strengthening by using carbon fiber polymer (CFRP). The experimental includes investigation eight (150*150*500mm) tested several load conditions. Variables considered in test program include; effect eccentricity and longitudinal reinforcement (Ø12mm or Ø6mm). Test results are d...
