“…The main structure is a 29 storey building, including 3 floors underground and 26 floors above ground. In this study, response spectrum, time history were executed combined by software ETABS, SAP2000, MIDAS/Gen and SATWE, and results were compared [6]. Similar studies on the comparison of symmetric RCC building with and without oblique columns shows more lateral resistance against seismic forces in building having oblique column [7], [8].…”

As the modern culture of living develops, conventional regular shaped buildings are getting outdated with new designs of complex irregular shaped structures. That irregularity became the new mode of measuring the modernity and development of that society. The complex shapes demands the need of designing irregular shaped structural elements too. One of that structural elements is oblique columns. The Oblique columns are inclined or slanted or rotated at an angle to reference line. Oblique columns are stiffer and the initial stiffness of the reinforced concrete frames largely depends upon the stiffness of oblique column. For oblique column of below 90°, there will be a decrease in plan dimensions and for above 90°, there will be increase in plan dimensions as we reach upper floors. It affects the lateral stiffness of these buildings. Compared to standard columns, oblique columns of below 90° have lesser storey shear values and oblique columns of above 90° have higher storey shear values. Stiffness of reinforced concrete frames with oblique columns depends on the distribution of oblique columns. The lateral loads are resisted by structure with oblique columns of below 90°, the highest storey displacement is less in oblique structure as compared to the easy RC Frame building. The building is analyzed with and without viscous dampers. In this review paper, attempts are made to review the previous studies related to buildings with oblique columns and dampers. It aims at consolidating the outcomes of several attempted kinds of research to improve the overall stability of the buildings with oblique column.

“…Nonlinear analysis is carried out on a 40-storey PPVC building with a height of 135.8 m to determine the structural responses under the actions of gravity, wind and seismic loads to evaluate its performance against the design limit states [12]. The nonlinear analysis considers geometric imperfections such as member and frame imperfections.…”

Singapore has adopted modular construction method known as Prefabricated Prefinished Volumetric Construction (PPVC), where this method requires modules to be prefabricated in a factory environment and subsequently transported to site for installation. A 40‐storey steel‐concrete composite PPVC building consisting of a modular structural frame and a central reinforced concrete (RC) core wall subjected to wind and seismic loading combinations are studied on the global response behavior building drift behavior. The case study is used to investigate the structural response behavior throughout the working life of the building under the service limit state. The adjacent modules are connected horizontally using a tie steel plate idealized by a pin‐pin connection while upper and lower modules are connected vertically using a vertical steel thread rod secured with locking nut idealized by a pin‐ended connection. The modules are braced to a central RC core wall. Continuous semi‐rigid floor diaphragm action is also considered in each floor. The study reveals the importance of inter‐module connection and the floor diaphragm action for the structural interaction between modules and central RC core wall.

Since the formation of the world, it is known that the earthquakes in seismic-active regions are occurring in sequences and from their results there are losses to millions of people and buildings. As Turkey is located in one of the worldꞌs most active seismic zones there are many studies for minimizing the damages especially at buildings during earthquakes. In this study, the seismic analyses were handled for a 10-storey unsymmetrical (L-shaped) building according to the Turkish Earthquake Code (TEC). These analyses contain the controls of A1-torsional irregularity, B2-weak-storey irregularity, relative storey displacements and second order effects. Furthermore, due to the lack of symmetry of the building, model was analysed for both +X and +Y directions. In order to correct irregularities which would occur in building models, the shear walls will be placed in different +X and +Y axles and positions and the analyses were repeated. According to the results for the case of an earthquake the safest and the most economical building model was suggested. Loads in all analyses in the study were calculated using "Equivalent Earthquake Loading Method" stated in TEC. The results will reveal a new look especially in the earthquake engineering.
