“…In such analyses, the suitable plan dimensions of a certain volume of soil under structures limited to the bedrock must be selected. The plan dimensions of the soil ( L and B in Figure ) were determined by trial and error, as presented in reference . Adequate values for these dimensions have been obtained to be as L = (100 m + d ), where d is the clear separation distance, and B = 40 m. In fact, it has been observed that for at least D x = 2.5 a in x ‐direction and D y = 0.5 a in y ‐direction, the structural responses are numerically stable and independent of soil medium dimensions.…”

“…For the near‐field zone, a secondary reduction is required to be applied on soil shear modulus, due to structural vibrations and inelastic soil–foundation interaction under earthquake excitation, which increase the cyclic soil shear strain values in the near‐field zone. A rigorous numerical model has been presented in reference to determine the near‐field dimensions and also the effective properties of the soil medium.…”

“…On the other hand, two adjacent buildings should not be so far away from each other so that the SSSI effects are eliminated. An adequate clear distance between two adjacent buildings ( d ) must be limited to a minimum value equal to the minimum distance for building separation ( δ MT according to IBC 2009 standard) and also a maximum value equal to half of the greater adjacent building width in plan ( a /2 where a is the greater adjacent building width ), which can be expressed as in Eqn 2 in the succeeding texts:

δ_{M T} \leq d \leq \frac{a}{2}

Abstract 8In cities and urban areas, building structures located at close proximities inevitably interact under 9 dynamic loading by direct pounding and indirectly through the underlying soil. Majority of the 10 previous adjacent buildings pounding studies that have taken the Structure-Soil-Structure Interaction 11 (SSSI) problem into account have used simple lumped mass-spring-dashpot models under plane-strain 12 conditions. In this research, the problem of SSSI-included pounding problem of two adjacent 13 symmetric in plan buildings resting on a soft soil pr...

A 2D model of two adjacent buildings with different heights (6 and 12 floors) and foundation levels without separation distance under seismic load and considering SSI is investigated. A special arrangement of contact elements (gap elements) each 1 m of the low height building in the contact zone is taken into consideration to fulfill all possible deformation contact modes which take place under seismic load (earthquake). Soil is modeled by 2D shell elements in contact with foundations of the two adjacent buildings. This paper focuses on the study of double pounding that takes place between the two adjacent buildings in some upper points at superstructure in the contact zone and also at foundation level. The forces of double pounding between the two adjacent buildings, which increase by softening of the soil, give a valuable assessment of straining actions of the two adjacent buildings and change the behavior of soil under the foundations and around basement floor.

Granites in Malaysia: From Hard Rock to Clay Minerals

et al. 2018

Tropical areas with extreme climates are host to extreme weathering processes and the weathered materials are normally left in situ with the absence of large-scale denudation processes such as glaciations. This research tries to understand the behaviour of the weathered granites in Malaysia, from hard rock to the final products, the clay minerals. Grade 1 or fresh granites were sampled from different locations in Malaysia and analysed. The residual soil above the fresh granites, which were formed from the weathering activities were also analysed. The types of clay minerals and clay-sized particle grains found from two study locations were compared. The bases of the comparisons were index properties, strength properties and the mineralogical properties. The parent rocks were also analysed to obtain the origin of the minerals formed at the later stages of weathering. It was found that the strength of the soil mass formed from the weathering processes generally depend on the clay-sized particle grains rather than the types of clay minerals. It should however be noted that only halloysites and smectites clay minerals were observed in the samples obtained from the two study locations.
