Evaluation of Seismic Performance and Soil-Structure Interaction (SSI) for Piloti-Type Buildings considering Korean Geotechnical Conditions by Seung Dae Kim, Jaeyong Yoon, Wanjei Cho, Jungwhee Lee

“…To achieve this goal, seismic SSI analysis applying the measured Gyeongju earthquake and design response spectrum (DRM) based on the architectural design codes are conducted by constructing three-dimensional structural analysis models with a five-story piloti-type building and four different soil properties: fill (FI), alluvial soil (AS), weathered soil (WS), and weathered rock (WR). From the analysis results, it is found that WS soil is largely affected by the seismic SSI, and the influence of the seismic SSI is different for each soil type regardless of the type of earthquake. …”

Developing new varieties of deep-rooted crops: silicon and agroecosystem services by Zimin Li, Yunqiang Wang, Zhaoliang Song

“…This enhancement is involved in three vital ecosystem processes: (i) increasing crop silicon uptake in deep horizons where it is more readily available as Si(OH4), (ii) contributing to storing more stable organic carbon at depth via root decomposition and deep pedogenic pathways, and (iii) accelerating CO2 transformation into stored or leached alkalinity via deep silicate weathering.…”
