Seismic analysis of semi-gravity RC cantilever retaining wall with TDA backfill

Il-Sang AHN, Lijuan CHENG

Frontiers of Structural and Civil Engineering 2017, Volume 11, Issue 4,   Pages 455-469 doi: 10.1007/s11709-017-0392-z

Abstract: The seismic behavior of Tire Derived Aggregate (TDA) used as backfill material of 6.10 m high retaining walls was investigated based on nonlinear time-history Finite Element Analysis (FEA). The retaining walls were semi-gravity reinforced concrete cantilever type. In the backfill, a 2.74 m thick conventional soil layer was placed over a 3.06 m thick TDA layer. For comparison purpose, a conventional all soil-backfill model was also developed, and the analysis results from the two models under the Northridge and Takatori earthquakes were compared. The FEA results showed that both models did not experience major damage in the backfill under the Northridge earthquake. However, under the Takatori earthquake, the TDA-backfill model developed substantially large displacement in the retaining walls and in the backfill compared with the soil-backfill model. Regions of large plastic strain were mainly formed in the TDA layer, and the soil over the TDA layer did not experience such large plastic strain, suggesting less damage than the soil-backfill model. In addition, the acceleration on the backfill surface of the TDA-backfill model decreased substantially compared with the soil-backfill model. If an acceleration sensitive structure is placed on the surface of the backfill, the TDA backfill may induce less damage to it.

An Integrated Analysis on the Synergistic Reduction of Carbon and Pollution Emissions from China’s Iron and Steel Industry

Quanyin Tan,Fei Liu,Jinhui Li,

Engineering doi: 10.1016/j.eng.2023.09.018

Abstract: pollution emissions (except for particulate matter emissions) could be achieved by 2025 under a high steel scrapHowever, subject to a limited volume of steel scrap, a focused increase in the EAF ratio with neglectionof the available supply of steel scrap to EAF facilities would lead to an increase carbon and pollution
