Three-Dimensional Seismic Nonlinear Analysis of Topography–Structure–Soil–Structure Interaction for Buildings near Slopes
(ASCE, 2022-3-1)It is essential to know the topography–soil–structure interaction (TSSI) for buildings adjacent to slopes. In the present study, the seismic response prediction of two midrise buildings located in the vicinity of slopes ... -
Estimation of Interface Parameter for One-Dimensional Consolidation with Continuous Drainage Boundary Conditions
(ASCE, 2022-3-1)In conventional consolidation theories, a boundary is simulated as either perfectly pervious or impervious, where the time-dependent drainage capacity at the boundary is ignored. Using the time-dependent impeded boundary ... -
Soil-Embedded Steel Baffle with Concrete Footing Responding to Collision by a Fallen or Flying Object
(ASCE, 2022-3-1)This article is concerned with the design of steel baffles embedded in soil to contain fallen boulders rolling down a hill slope, with the buried segment of the baffles cast into concrete. Analytical solutions presented ... -
Active Earth Pressure of Finite Width Soil Considering Intermediate Principal Stress and Soil Arching Effects
(ASCE, 2022-3-1)Traditional earth pressure theories are based on the assumption of semi-infinite space. The existence of intermediate principal stress and soil arching effects is ignored, which will cause significant errors in the application ... -
Recycled Aggregate Mixtures for Backfilling Sewer Trenches in Nontrafficable Areas
(ASCE, 2022-3-1)Sewer infrastructures that are backfilled with available onsite expansive soils may be exposed to damages due to seasonal ground movements. Therefore, for deep excavated trenches located in nontrafficable areas, the ... -
Rainfall Infiltration and Water-Retention Characteristics of Rockfill Material
