The optimization of civil structures is a technique whose purpose is to efficiently use the materials that make up the structural systems based on previously established restrictions and objectives. The use and development of these techniques has been closely linked to technological advance since, through the use of computer equipment, complex mathematical models can be solved with low cost and time. This article presents OPS Design v2.0, a computer tool that allows obtaining a preliminary optimal distribution of metallic structural profiles in a Non-Braced Frame System (OMF: Ordinary Moment Frame). The optimization model implemented in OPS Design v2.0 seeks to minimize the number of different profiles and the structure's own weight in order to reduce the construction complexity and the weight per linear meter (costs in quantities of material). To evaluate its effectiveness, a case study was developed where it was concluded that the designs produced by the application are more efficient than those obtained by commercial tools, thus reducing the computational expense and time used by designers in iterative processes that are carried out in the initial phases project.
土木结构优化是一种技术，其目的是根据先前确定的限制条件和目标，高效利用构成结构系统的材料。这些技术的使用和发展与技术进步紧密相连，因为通过使用计算机设备，可以低成本、高效率地求解复杂的数学模型。本文介绍了OPS Design v2.0，这是一种计算机工具，可用于在无支撑框架体系（OMF：普通弯矩框架）中初步获得金属结构型材的最优分布。OPS Design v2.0中实施的优化模型旨在尽量减少不同型材的数量和结构自身重量，以降低施工复杂性和每延米重量（材料用量成本）。为评估其有效性，开展了一个案例研究，得出的结论是该应用程序生成的设计比商业工具获得的设计更高效，从而减少了设计师在项目初始阶段进行的迭代过程中的计算成本和时间。
