Four precast column-to-foundation connection specimens, previously tested under lateral reversed cyclic loading and constant axial load (first-stage tests), were repaired with Carbon Fibre Reinforced Polymer (CFRP) layers in the areas where plastic hinges had formed retested same loads (second-stage tests). The columns originally manufactured ultrahigh-performance concrete (UHPC) high stee-fibr...

In order to realize the design concept of “strengthened column and weakened beam, strengthened connection joints components” ensure improvement joints’ bearing capacity transfer plastic hinges along beams far away from ends, this paper proposes a new type prefabricated with strengthen-weaken beam-column connection, changes multiple parameters. Six joint models are designed for finite element an...

Precast load-bearing shear wall panels are used extensively for high-rise construction because of the ease and speed of assembly, and the high quality of the precast panels. The connections between panels are extremely important since they affect both the speed of erection and the overall integrity of the structure. This paper presents the results of a research program conducted to investigate ...

Precast load-bearing shear wall panels are used extensively for high-rise construction because of the ease and speed of assembly, and the high quality of the precast panels. The connections between panels are extremely important since they affect both the speed of erection '~md the overall integrity of the structure. This paper presents the results of a four-year research program conducted to i...

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...

Abstract The paper shows the results of an experimental campaign aimed at investigating cyclic behavior a column-to-foundation joint for precast concrete elements. tested connection is realized adopting corrugated steel ducts embedded into foundation, in which column protruding rebars are anchored by grouting high performance mortar. program consists testing six full-scale reinforced square-sec...
