STUDY ON SEGMENT WIDTH OF FLAT-TYPE REINFORCED CONCRETE SEGMENT

Shake Table Tests of Reinforced Concrete Flat Plate Frames and Post-tensioned Flat Plate Frames

A research study was undertaken to assess performance of flat plate systems constructed with slab shear reinforcement under dynamic loads. The research program consisted of shake table tests and accompanying analytical studies of two, approximately one-third scale, two-story, two-bay, slab-column frames. One specimen was constructed with reinforced concrete (RC) slab, whereas the other specimen...

Effects of Vertical Ground Motion on Seismic Performance of Reinforced Concrete Flat-Plate Buildings

Shear Capacity of Reinforced Concrete Flat Slabs Made with High-strength Concrete: A Numerical Study of the Effect of Size, Location, and Shape of the Opening (TECHNICAL NOTE)

Nowadays, concrete with strength higher than 50 MPa is utilized due to the ever increasing need for higher strength and prolonged healing properties. Despite the widespread use of high-strength concrete, only a few research projects have been conducted on the punching shear strength of high-strength concrete slabs. Reinforced concrete flat slabs are widely employed in structural systems. The lo...

The Influence of DC-Link Voltage on Commutation Torque Ripple of Brushless DC Motors with Two-Segment Pulse-width Modulation Control Method

The commutation process causes current ripple to be generated in the drive system of brushless DC (BLDC) motor. This, in turn, leads to output torque ripple. Mechanical vibration and acoustic noise are its influences which are undesirable phenomenon in some applications. A new method is presented in this paper which reduces torque ripple and commutation period in the entire range of motor speed...

On a new segment-to-segment contact algorithm

A new contact algorithm is presented which satisfies both stability and the contact patch test. The segment-to-segment algorithm involves a contact pressure interpolation and an accurate integration of the contact constraints over the surfaces of the contacting bodies. Numerical integration is carried out over sub-segments based on the element topologies of both contacting surfaces. The algorit...
