Effect of eccentricity in reinforced concrete beam-column-slab connection under cyclic loading

Rooh ULLAH, Amjad NASEER, Muhammad FAHIM, Mohammad ASHRAF, Eid BADSHAH

Frontiers of Structural and Civil Engineering 2021, Volume 15, Issue 2, Pages 390-398 doi: 10.1007/s11709-021-0690-3

Abstract: The horizontal eccentricity ( ) is maintained at 12.5% and 25% of column width ( ) for specimens 1 andIt is concluded that the eccentricity has no significant effect on the lateral load carrying capacity; however, the overall strength degradation increases with the increase in eccentricity.Similarly, the elastic stiffness of specimen 2 decreased by 14% as the eccentricity increased from 12.5%to 25%; however, the eccentricity had no significant effect on the overall stiffness degradation.

A composite optimization method for separation parameters of large-eccentricity pico-satellites None

Lai TENG, Zhong-he JIN

Frontiers of Information Technology & Electronic Engineering 2018, Volume 19, Issue 5, Pages 685-698 doi: 10.1631/FITEE.1700416

Abstract: method, which combines angular velocities with external moments for separation parameters of large-eccentricityresults show that the optimization method can effectively optimize the separation parameters of large-eccentricityand non-stable status elastic parameters, the distribution of all kinds of elastic devices, and large-eccentricity
