“…To evaluate the accurate dynamic response of the superstructure it is needed to consider the substructure system and the soil supporting structure in the soil-structure interaction (SSI) analysis. Due to the lack of detailed guidelines in the local design codes, overlooking or incorporating the subterranean levels in the seismic resistance design of building structures is still a controversial issue [1][2]. When a building rests on a shallow foundation and is subjected to lateral seismic loads, it is reasonable to crop the superstructure and analyze it as a fixed base structure at ground level with free-field ground motion excitation since free-field motion is approximately equal to foundation input motion.…”

“…The SSI characteristics of structures supported by shallow and deep foundations have received the majority of researcher's attention in the last few decades. However, fewer studies [2] have been presented in the literature on buildings with subterranean levels that incorporate seismic SSI utilizing an experimental and simplified three-step method (substructure approach). In the analysis of the seismic SSI response of any particular problem, numerical techniques are highly capable of incorporating different combinations of effects and nonlinearity resulting from material behaviour and changes in geometry, material nonhomogeneous properties, soil-structure interface conditions, radiation and material damping changes, as well as strong ground motion [3].…”

The dynamic response of reinforced concrete moment resisting frame (RC-MRF) building structures is mostly altered by the substructure system such as the type of foundations and features of subterranean levels, as well as subsurface soil conditions. The majority of low-to high-rise buildings, in urban areas, are designed with one or multi-level subterranean levels for parking and other services. However, many designers overlooked incorporating these subterranean levels and soils in the seismic resistance analysis assuming that the building is fixed at the ground surface. The present study assessed the effect of the subterranean levels on the dynamic response of RC-MRF buildings. Several two-dimensional (2D) nonlinear finite element seismic response analyses were carried out in ABAQUS software for medium-rise buildings without and with one to multi-level subterranean levels resting on a deep homogenous soft soil profile under the effect of strong seismic input motion. It was observed that the subterranean levels considerably alter the dynamic characteristics and demands of the building structures. Hence, explicitly incorporating the subterranean components and foundation soil during the seismic resistance design of building structures is important.

“…The stability of the retaining wall is obtained mainly from the self-weight of the structure and the weight of the soil above the foundation plate. The magnitude and distribution of earth pressure on the retaining wall depend on the movement of the soil relative to the wall (Tadesse et al, 2022).…”

Jayapura City is one of the Papua Province’s capital cities with an increasing population. One of the areas in Jayapura City, especially Perumnas IV Padang Bulan, is surrounded by hills. Infrastructure development in the densely packed Perumnas IV Padang Bulan area and increasingly narrow land has forced the local community to build infrastructure under the foot of the hills. Infrastructure development under the foot of the mountains is very prone to landslides or soil movement. There is a retaining wall planned so that the movement of the soil is restrained by the retaining wall so that no landslides occur, which endanger the community in the Perumnas IV Padang Bulan area. From a survey of the Perumnas IV Padang Bulan area in the form of topographic data and cone penetration data (CPT), contour data and cone penetration results (CPT) data were obtained for QC and fs values, then soil type classification was carried out with empirical correlation approaches, then active earth pressure calculations were carried out and passive from Rankine’s theory. As well as planning a safe leaning type retaining wall. From the results of the planning that has been done, the plan obtained is a leaning type retaining wall with concrete material, the height of the retaining wall reaches 3.1 meters, and the width of the foundation is 2 meters. Safe against overturning, shearing, and soil-bearing capacity.
