厂房建筑在工业建设中所占投资比重很大,一般为整个基建投资的30～40％,如何在保证安全、满足使用的前提下,尽可能地降低厂房造价,一直是土建结构研究、设计人员要解决的主要课题之一。在工业厂房中,采用桥式起重机的单层厂房最为普遍。单层厂房结构主要受到风、雪、吊车和建筑结构自重等外力的作用。吊车梁完全承受吊车荷重,柱子及基础主要承受风荷重和吊车荷重。设计柱子,弯矩是主要控制因素,而风力和吊车横向水平力引起的弯矩大约各占一半。由此可见,吊车对单层厂房结构的影响是很大的。但是以往设计起重机(即吊车)的,不了解设计厂房结构的情况,只按本专业的合理性进行设计;
The factory building accounts for a large proportion of the investment in industrial construction. It is generally 30-40% of the entire infrastructure investment. How to reduce the cost of the factory building as far as possible while ensuring safety and meeting the needs of use has always been the research and design of civil engineering structures. One of the main topics to be solved. In industrial plants, single-floor buildings using bridge cranes are the most common. The structure of a single-storey factory building is mainly affected by external forces such as wind, snow, cranes, and the weight of building structures. The crane beam fully bears the load of the crane. The pillars and the foundation mainly bear the wind load and the weight of the crane. In designing the column, the bending moment is the main controlling factor, and the bending moment caused by the wind and the lateral horizontal force of the crane is about half. It can be seen that the effect of the crane on the structure of a single storey building is significant. However, in the past, cranes (ie, cranes) were designed without knowing the design of the plant structure and were only designed according to the rationality of the profession.
