The utility model discloses an arc shape processing device for reinforcing bars. The device comprises an operating disc of a reinforcing bar bending machine and is characterized in that the device also comprises bending pin shafts and stop iron forming shafts, wherein the number of the bending ...
The theoretical justifications for choosing W-shape rebar as shear reinforcement over other geometric shapes lie in its enhanced shear strength, improved bonding characteristics, ductility, simplified construction, compliance with codes, material efficiency, and suitability for seismic applications [80,81]....
Given that the current seismic codes are only based on single earthquakes [1,2], thus, considering the effects aftershocks on seismic investigations is of paramount importance. Several efforts have been directed on assessment of structures subjected to multiple earthquakes, including SDOF systems [3–...

Non-CG methylation is abundant in plants, but its functions are poorly understood. A new study has uncovered the contributions of each non-CG methyltransferase, including the poorly characterized methyltransferase CMT2, to DNA methylation patterning and
And, where insurance codes permit, additional sprinklers can often be eliminated. Standard panels are available in widths of 2', 3' or 4'. S.No. Grating Specification (Standard Panel) Load Bar Type : Serrated Cross Bar Size : 6mm twisted Square Size : 6m x 0.905m Finish...
In general, the Fe-SMA bars presented similar bond performance as conventional steel bars. However, the bond strength of unconfined specimens was reduced with the activation temperature. For confined specimens, the activation temperature had a minor effect on the bond strength. Local bond stress-...

Welding of NiTi alloy to steel is however not straightforward with standard ...
The common deficiencies in RC beam-column joints include poor-quality concrete and lack of shear reinforcement, especially in structures designed and constructed before the development and implementation of modern seismic design codes. Such joints are expected to experience severe permanent damage under ...
The UMAT subroutine codes are implemented on the analysis program so as to numerically reproduce the behavior of the superelastic SMA materials. The FE models for steel slit dampers are calibrated to the established test data for the purpose of obtaining reliable prediction. The history outputs used...
