Research on structural scheme optimization and dynamic calculation of a candy factory

以具体实例为研究对象,从楼盖布置、方案分析、荷载及动力计算这四个方面,进行了方案比较及计算规律的总结。通过强度、材料用量、适用性的比较,得出了一种新型的楼盖布置方式。通过改变梁、柱截面大小的比较,得出长宽比>3的结构,周期调整及其与造价间的规律。通过设备、叉车等效活荷载的计算,得出相同重量不同外形尺寸,作用在相同板跨;和相同重量及外形尺寸,作用在不同板跨,楼面等效活荷载的变化规律。动力荷载的计算,得出转子质量与规范规定的振动线位移及速度间限值的变化规律。该工程的分析与计算对大跨度楼盖、长宽比>3的结构、设备等效活荷载及动力计算都具有一定的指导与借鉴作用。

Taking a specific example as the research object, the scheme comparison and calculation law are summarized from the four aspects of floor layout, scheme analysis, load and dynamic calculation. Through the comparison of strength,material consumption and applicability, a new floor layout is obtained. Through the comparison of changing the section size of beam and column, the structure with length width ratio > 3, cycle adjustment and its relationship with cost are obtained. Through the calculation of equivalent live load of equipment and forklift, it is obtained that the same weight and different overall dimensions act on the same slab span;And the same weight and overall size, acting on different slab spans, the variation law of floor equivalent live load. Through the calculation of dynamic load, the variation law between the rotor mass and the limit value of vibration linear displacement and speed specified in the code is obtained. The analysis and calculation of the project can be used as a guide and reference for long-span floor, structure with length width ratio > 3, equivalent live load of equipment and dynamic calculation.
