First, the concept of the structure optimization design:
It mainly includes the selection of structural system, the selection of building site, the rationalization of building shape and building layout. It is required that the structural optimization design should be involved in the determination of the building plan. Choosing a reasonable system, adopting the most regular plane form as possible, avoiding large openings and large overhangs, and sudden changes in façade stiffness, can not only greatly improve the safety performance of the structure, but also the top priority of structural design and structural optimization design, which is particularly important to save construction costs.
2. Optimal design of main components;
It mainly includes the layout of the structure, the selection of building materials, the selection of component size, and the rationalization of the reinforcement configuration. For a reasonable structural design, most of the component reinforcement should be within the range of reasonable structural reinforcement. Blindly increasing the reinforcement is not a good thing.
For example, the purpose of a strong column and a weak beam is to let the beam fail first to ensure that the column does not fail to prevent the overall collapse of the structure. If the designer does not understand the intent of the specification and solves the safety problem by blindly increasing the amount of materials, thinking that the structure is safer, it actually has the opposite effect and makes the structure more unsafe.

Optimum structural design (optimum structural design) is to find the best design scheme according to a certain goal (such as the lightest weight, the lowest cost, the maximum stiffness, etc.) under the given constraints, which was once called the optimal design of the structure or the optimal design of the structure, and is also called the "structural synthesis" compared to the "structural analysis"; If the weight of the structure is minimized, it is called a minimum weight design.
There are several categories of design: graphic design, web design, environmental design, GUI design, illustration design, animation design, product design, architectural design, fashion design, etc.
The structural design is more professional and requires higher basic knowledge. There is no good prospect for a zero-based basic academic structure. >>>More
What you are talking about should be standard bricks, 240 * 115 * 53 The volume of each brick (240 * 115 * 53) = cubic meters (the gross consumption is calculated according to its volume), and we are now calculating the net consumption, plus 1% loss. That's the actual amount, 120 walls. **Cubic metre. >>>More
The lifting method is not the same, the algorithm is not the same, generally according to the principle of moment balance, pay attention to check the lifting to the maximum angle when the goods are not unloaded.
8 guiding principles: the principle of objectives, the principle of conformity, the principle of responsibility, the principle of organizational hierarchy, the principle of management range, the principle of specialization, the principle of coordination and the principle of clarity.
