Shear Wall Designs In5~#High-rise Building Of Botou Century Garden

High-rise buildings are becoming the trend of the development of urbanconstruction， with sustained growth in urban population density and increasingcontradiction between residential demand and land area by year. Shear wall structure iscommonly used in high-rise building structure types with big stiffness, good wholenessand stronger ability to resist lateral group advantages under earthquake and wind load.Different shear wall structure forms impact on the natural vibration period of structure,modal analysis, the vertex displacement, the interlayer displacement, internal forcecalculation and reinforcement configuration directly, thus affecting the project cost.Here two design schemes of shear walls are applied in a high-rise building in5#high-rise building of Botou century garden. Scheme1is for the layout of odd-shapedcross section’s shear wall. In order to keep the stiffness from two directions whiledecreasing the displacement as well as the deviation, a lot of T-type and L-type shearwalls are applied, especially in join connects and sides for stairways and fire lift lobbies.Scheme2is mainly for the layout of off-shaped shear wall structure and partly aboutnormal shear wall. L-type is applied instead of T-type while the numbers of odd-shapedshear walls are necessarily diverse in different parts. Since the current designs forodd-shaped shear walls are not skillful enough, there are some problems such as complexcomputation in the odd-shaped shear walls, overlarge internal forces, overuse of steelconsumption and complex construction.This paper calculated two kinds of primary scheme of mechanical response underthe action of the wind load and earthquake with SATWE software and compared the twokinds of schemes of vibration period, the maximum earthquake force function anddirection, the displacement and interlayer displacement, the interlayer displacement angle,floor shear force, bending moment, etc. By analyzing the comparison results, the authorchose scheme2for the final design plan under the consideration of design requirementsand the project cost.The results and conclusions in the present paper can provide valuable references forthe structural design of similar high-rise buildings.
