Structural optimization design: Under given constraints, find the best design solution based on a certain goal (such as the lightest weight, lowest cost, maximum stiffness, etc.), which was once called the optimal design of the structure. Or structural optimal design, current optimization problems basically use asymptotic mathematical methods. Of course, for simple problems, practical engineering problems can be transformed into mathematical problems for computer processing. However, buildings are generally very complex, which is also the difficulty in architectural optimization. According to the reliability optimization method, when selecting high-rise building structures in non-seismic disaster areas, priority should be given to structural systems with better wind resistance, that is, building structural systems with smaller wind pressure body coefficients.
Optimization of steel bars. The floor slabs are arranged in a distributed manner, and the longitudinal steel bars of the beams are changed to the longitudinal bars of different diameters and the vertical bars of the entire length, thereby reducing the beam steel bars. Optimization of foundations and baseboards, especially basements. For areas with good soil layer, the soil layer where the base plate is located may be the rock layer, and the groundwater is deep under the base plate. In this case, the rock layer can be directly used as the structural base plate. Optimized design of detailed nodes. Detailed details, such as the design optimization of facade moldings, overhangs, ring beams, and ceilings, are often overlooked by designers. But it is also an important part of the construction cost. Implement strict controls to avoid additional waste beyond non-computing requirements.
Meet economic requirements. That is to say, the structural design should be based on the construction location, scale, height, etc. of the building, and on the premise of meeting the requirements of durability, safety and usability, careful calculation should be made to adopt an economical and reasonable optimized structural system to save costs. . At present, many construction projects require large investments and long construction cycles. Therefore, effective structural optimization design can reduce the investment amount accordingly. Optimizing the design of building structure is a key means to realize the function of the building itself and the construction investment cost.
Considering the necessary structural measures, the results of structural design are reflected in the structural construction drawings drawn. This drawing is the language of the structural engineer and is directly facing the construction site and related engineering and technical personnel. It should be carried out in accordance with certain specification drawing.
