strength and stiffness as compared with double diagonal strut models Therefore, masonry infill panel can be a good solution to model masonry infill, however, it depends on the importance of structure and type of design it has to be modeled It obtains that the steel bracing system at soft storeys effectively contributes to the structural stiffness of high-rise building Building in this project is using shear wall – core system, so double diagonal strut model cannot be used in this model Masonry infill panel is also proved that it is a reliable solution Therefore, masonry infill panel is used to simulate masonry for the project building Analysis project building 10.4.1 Model considered for analysis Following three models are analyzed in ETABS 20 using equivalent static analysis, response spectrum analysis Model 3: Original modeled building with masses of the walls included Model 4: Building has full brick masonry of 200mm thick with no brace at service floor and technical floor Masonry infill is modelled as four nodded quadrilateral shell elements Model 4a: Building has full brick masonry of 200mm thick with steel brace at service floor and technical floor Masonry infill is modelled as four nodded quadrilateral shell elements Figure 10-8 Isometric view of model (Refuge floor) Student: Lê Đức Việt ID: 18149345 MASONRY INFILLS & SOFT STORY EFFECT Figure 10-9 Isometric view

(X-Direction) U2 for Transverse (Y-Direction) Figure 10-13 Define load case for response spectrum analysis ➢ Scale factor in RSA After analysis, we must review the base shear due to all modes, reported in the Response Spectrum Base Reaction Table If the dynamic base shear reported is more than 85% of the static base shear, then there is no further action However, if dynamic base shear is less than 85% of the static base shear, then the scale factor should be adjusted to make the responsespectrum base shear matches 85% of the static base shear In this case, the new scale factor can be summarized like this: 𝐼𝑔 static base shear × 0.85 × 𝑅 response spectrum base shear With 𝐼𝑔 /𝑅 is the response-spectrum scale factor Analysis should be rerun with this scale factor specified in the response-spectrum case 10.4.3 Analysis of the building All results showed in Longitudinal direction (X-Dir), find results in Transverse direction (Y-Dir) in Appendix Student: Lê Đức Việt ID: 18149345

Seismic base shear is considerably more for masonry infill models as compared with bare frame model while storey drifts and storey displacements significantly reduce Hence the presence of non-structural masonry infill will increase strength and stiffness of structure when subjected to lateral seismic loading Models with soft stories have got highest storey drift values at soft stories levels, which leads to dangerous sway mechanism Therefore, providing steel brace is essential so as to avoid soft storey failure Storey displacement and drift in static analysis values are more compared to dynamic analysis values of same model Steel cross bracings effectively increase the storey stiffness and slightly reduces the maximum inter story drift, lateral displacement of reinforced concrete building Conclusion: The enhancement of infill and soft storey irregularity effect should be considered in the analysis of high-rise building design Student: Lê Đức Việt ID: 18149345 171
