This research provides a practical and feasible retrofitting solution for soft story in reinforced concrete (RC) buildings with masonry infill walls for example in Nepal through numerical analysis. It is well understood that stiffness and strength of the soft story floor can be increased significantly by adding RC shear wall in the frame opening of the ground floor, making lateral deformation of that floor negligible. With this consideration, the authors have developed a numerical optimization framework for optimizing the RC shear wall in the open floor of soft story building incorporating socio-technical aspects from their previous publication [Timsina, K., Gadagamma, C. K., Numada, M. and Meguro, K. [2019b] “Development of a numerical optimization framework for solving soft-story problem in reinforced concrete frame buildings,” Seisan-Kenkyu]. The objective function for numerical optimization is cost minimization with the constraints of usability, performance, and complexity from a detailed field study. In this paper, the numerical optimization framework is developed and solved using the sequential quadratic programing (SQP). The whole scheme has been incorporated inside the 2D-Applied Element Method (AEM). The retrofitting solution thus obtained from the numerical optimization has been analyzed using the incremental dynamic analysis to know the capacity of the frame structure in earthquake ground motion. It shows that the retrofitting method can significantly enhance the soft story frame’s capacity and ensure the dwellers’ interests are not compromised.
本研究通过数值分析，为尼泊尔等国采用砌体填充墙的钢筋混凝土（RC）建筑的软弱楼层提供了切实可行的改造方案。众所周知，通过在底层框架开口处增加钢筋混凝土剪力墙，可以显著提高软弱楼层的刚度和强度，使该楼层的侧向变形可以忽略不计。考虑到这一点，作者开发了一个数值优化框架，用于优化软弱楼层建筑开敞楼层中的 RC 剪力墙，该框架结合了他们之前发表的社会技术方面的内容[Timsina, K., Gadagamma, C. K., Numada, M. and Meguro, K. [2019b] "Development of a numerical optimization framework for solving soft-story problem in reinforced concrete frame buildings," Seisan-Kenkyu]。数值优化的目标函数是成本最小化，并通过详细的实地研究确定了可用性、性能和复杂性等约束条件。本文开发了数值优化框架，并使用顺序二次编程（SQP）进行求解。整个方案已纳入二维应用元素法（AEM）。通过增量动态分析，对数值优化得到的改造方案进行了分析，以了解框架结构在地震地面运动中的承载能力。结果表明，改造方法可以显著提高软弱楼层框架的承载能力，并确保居住者的利益不受损害。
