，正确设计和计算禹城钢结构的承载能力是防止整体失稳的基础。在设计过程中，必须仔细考虑结构的荷载情况、支撑系统和材料的性能等因素。合理选择合适的断面形状和尺寸，确保结构具有足够的强度和刚度，能够承受设计荷载并保持稳定。

Firstly, the correct design and calculation of the bearing capacity of Yucheng steel structure is the foundation for preventing overall instability. In the design process, it is necessary to carefully consider factors such as the load situation of the structure, the performance of the support system and materials. Reasonably select the appropriate cross-sectional shape and size to ensure that the structure has sufficient strength and stiffness to withstand design loads and maintain stability.

其次，加强禹城钢结构的连接和支撑是防止整体失稳的重要措施。通过采用适当的连接方式和技术，确保连接节点的可靠性和刚性，避免松动和变形。同时，在设计支撑系统时，要考虑结构的整体稳定性，采用合理的支撑形式和位置，增加结构的抗侧移和抗倾覆能力。

Secondly, strengthening the connection and support of Yucheng's steel structure is an important measure to prevent overall instability. By adopting appropriate connection methods and techniques, the reliability and rigidity of the connection nodes are ensured, avoiding looseness and deformation. At the same time, when designing the support system, the overall stability of the structure should be considered, and reasonable support forms and positions should be adopted to increase the structure's resistance to lateral displacement and overturning.

此外，定期进行结构检测和维护是保持禹城钢结构整体稳定的必要措施。定期检查结构的受力状态、连接状况和变形情况，及时发现和处理潜在问题。同时，进行适当的防腐蚀处理和修复，延长禹城钢结构的使用寿命。另外，对于一些长期受到冲击和振动的禹城钢结构，还应考虑采取相应的减震和防护措施，提高结构的稳定性。

In addition, regular structural testing and maintenance are necessary measures to maintain the overall stability of Yucheng's steel structure. Regularly inspect the stress state, connection status, and deformation of the structure, and promptly identify and address potential issues. At the same time, appropriate anti-corrosion treatment and repair should be carried out to extend the service life of Yucheng steel structure. In addition, for some Yucheng steel structures that have been subjected to long-term impact and vibration, corresponding shock absorption and protection measures should also be considered to improve the stability of the structure.

综上所述，通过正确的设计、加强连接和支撑，以及定期检测和维护，可以有效防止禹城钢结构整体失稳，提高建筑的性。对于建筑设计和施工人员来说，理解和应用这些防止措施关重要。

In summary, through correct design, strengthened connections and supports, as well as regular inspection and maintenance, the overall instability of Yucheng steel structure can be effectively prevented, and the safety of the building can be improved. Understanding and applying these preventive measures is crucial for architectural designers and construction personnel.
