Testing of reinforced concrete shear wall boundary elements design according to ACI-318Flintrop, Anna
19). This is an absolutely minimum shear wall structure. The two shear walls are shaped to meet the architectural requirements of the building without extending beyond the plan limits of the base of the building. It is interesting to compare this example with Table I in the Arup paper. ...
However, if an event, such as an earthquake beyond the normal design basis occurs, both the shear wall structure and SNML facility may be damaged. Normal or extreme wind loading on the building will result in regions where the external pressure is less than the internal pressure, which may ...
I feel like I saw one with shear friction at the base of a shear wall... that would involve moment/tension on the one end of it, it also involved a particularly large Ac. Also, that particular Hilti example isn't that for a slab splice? Not sure I follow that PPI example, they'r...

Use of simple performance-based design approaches provides an ideal framework to incorporate code changes that balance performance expectations and impact/cost.John W. WallaceUniversity of California, Los Angeles
Shear wallACI 318Detailing90-degree hooksObserved wall damage in recent earthquakes in Chile (2010) and New Zealand (2011), where modern building codes exist, exceeded expectations. In these earthquakes, structural wall damage included boundary crushing, reinforcement fracture, and global wall buckling...
How you design your wall depends on the height to length ratio. Squat shear walls are designed differently to tall walls (that have an aspect ratio > 1.5-2.0). So it is not just the thickness and length that is important, you need to consider the aspect ratio of the wall and reinforce...
Using the test results, the minimal value of 𝜂η for the flexural design of insulation panels was determined. Additionally, the safety of the ACI 318-19 [11] specification in predicting cracking moment capacity in the elastic state and nominal moment capacity in the ultimate state was ...
Bischoff [17] calculated the deflection of tilt-up concrete wall panels under service load. Bischoff [18] also compared his own formula, adopted in ACI 318-19, with the approaches of Branson and Europe. The deflection of RC beams is affected not only by bending but also by shear. In ...
