Results of an experimental investigation of the seismic performance of prefabricated column-footing connections are presented. Tests were conducted on six 1/4-scale prefabricated column specimens inserted into prefabricated footings in two Groups. Group-1 consisted of four specimens, which were tested under constant axial load and cyclic inelastic lateral displacements. The remaining two specim...
Glue joints are more useful in Aerospace so in this article we presented new method for glue joint. In this method the maximum stresses that occurs at the edges of the bottom glue joint and cause ultimate failure in this type of connection is Decrease and increase the glue joint strength. In this method glue in the area overlapping the discrete and separate column considered Also, the connectio...
In this study, the behavior characteristics of I beam-to-concrete filled tube (CFT) column connection is studied through experiment and finite element models under the monotonic loading. To validate the finite element modeling, at first, an experimental model is made and experimented. After validation of the finite element modeling, different models were created in the software. The studied par...
Influence of abutment and connection type on implant-abutment connection rigidity: an in vitro study
Objectives: To evaluate the effects of abutment material and connection type on implant-abutment rigidity. Methods: The study evaluated eighteen implants with three different types connections: external-hexagon, tri-channel, conical connection. Half were connected to titanium abutments, other half zirconia forming six groups (n=3). submitted 1,200,000 load cycles a force amplitude 90 N. During ...
Background and Aim: Maintaining the primary torque of the abutment screw is a common problem related to implant-supported restorations; a failure in this respect often leads to screw loosening. The abutment screw plays a critical role in the long-term stability of restorations. This study aimed to assess the effect of two abutment connection types with and without cyclic loading on removal torq...
the concepts of similarity and dissimilarity have been the interest of many researchers. basically, in the studies the similarity between two objects or phenomena, has been discussed. in this thesis, we consider the case when the resemblance or similarity among three objects or phenomena of a set, 3-similarity in our terminology, is desired. later we will extend our definitions and propos...
