2 Ιουλ 2021 · This study has presented a series of quasi-static tests aimed at investigating the behavior of the novel precast RC shear walls under cyclic loading, and evaluating the influence of slot length and number of friction-bearing devices on the cyclic performance of precast RC shear walls.
25 Ιουν 2018 · Performance of reinforced concrete (RC) walls in recent laboratory tests and in recent strong earthquakes has revealed that thin wall boundaries are susceptible to concrete crushing,...
The primary aim of the testing was to obtain reliable pull-out values for various types of fixings and anchors located within the slots, as these are perceived as the weakest portion of the block for the location of fixings and anchors.
Quality Tests on Fresh Concrete. Most Common Quality Tests on Fresh concrete are: 1. Workability Tests. Workability of concrete mixture is measured by, Vee-bee consistometer test, Compaction factor Test, and Slump test. Read More: Vee-bee consistometer test, Compaction factor test, Slump test. 2.
22 Ιουλ 2019 · 7 Citations. Metrics. Abstract. This study aimed to investigate the effects of small openings on the structural performance of reinforced-concrete (RC) structural walls. Cyclic lateral loading tests were conducted on five RC walls with an aspect ratio of 2.6 and small openings. The main test parameter was the size of the small openings.
