A colleague working with you in the same design office has completed a seismic analysis and design for a 5-story reinforced concrete building that satisfies all the checks according to Eurocode 8. However, subsequently, when preparing the drawings he decides to reduce the height of each story (e.g., from 3.5m high to 2.5m high) thinking that this will make the building safer. What comments do you have for them? When designing a building structure in a seismically active area you have the choice of placing the same structure (i.e., geometry, member sizes and material properties) at two possible sites: (a) soft soil ground, or (b) stiff rocky ground. What possible differences would you expect in their potential seismic response? Consider the following simple soil stratigraphy shown in Figure Q4c. The angle of incidence of an SH wave at layer 6 is i6=87º. At what angle (₁) do you expect this wave to arrive at the ground surface? TIK i6 = 87⁰ Layer 1 P₁ = 900 kg/m³ G₁ = 35 MPa Layer 2 P2 = 1200 kg/m³ G₂ = 70 MPa Layer 3 P3 = 1350 kg/m³ G3 = 90 MPa Layer 4 P4 = 1750 kg/m³ G4 = 110 MPa Layer 5 Ps 1900 kg/m³ G5 = 170 MPa Layer 6 P6 2100 kg/m³ G6 = 190 MPa Figure Q4c A colleague working with you in the same design office has completed a seismic analysis and design for a 5-story reinforced concrete building that satisfies all the checks according to Eurocode 8.
