Many recent research studies have focused on developing innovative seismic-resilient structural systems to reduce repair costs and downtime in the aftermath of an earthquake. In this regard, dealing with steel Moment Resisting Frames (MRFs), works demonstrated benefit deriving from adoption both low-damage self-centring column base connections, terms damage residual drifts reduction. Although s...

The SidePlate moment connection system, developed by MNH-SMRF Systems, Inc., looks different because it is different. SidePlateTM's unique trademark geometry provides physical separation between the face of column and end of beam by means of parallel full-depth side plates. This innovative feature ensures the elimination of all brittle behavioral uncertainties responsible for the unprecedented...

this paper focuses on using the recently developed extended finite element model for buckling analysis of edge cracked columns under concentric axial load. the effect of crack depth and its location on the carrying capacity of columns is studied. the effect of different boundary conditions is also investigated. numerical examples are offered to show the efficiency and effectiveness of the propo...

In this work modelling and experimental validation of an integrated process for the removal of carbon dioxide from ammonia solutions is presented (decarbonisation). In this process, carbon dioxide is stripped out from the solution simultaneously with small amounts of ammonia at ambient pressure in a packed column. Recovery of the stripped ammonia can be reached by combining absorption of ammoni...
