The comparative body model in material and geometric nonlinear analysis of space R/C frames

Boris Trogrlic, Ante Mihanovic

This paper aims to present a new numerical model for the stability and load‐bearing capacity computation of space reinforced‐concrete (R/C) frame structures. Both material and…

Determination of cable tensions based on frequency differences

Wei‐Xin Ren, Hao‐Liang Liu, Gang Chen

Owing to the cable flexibility, it is practically a lot easier to measure the high‐vibration frequencies of the cable than the fundamental vibration frequency. The objective of…
