MODAL ANALYSIS OF MULTI-RIB SLAB LIGHTWEIGHT FRAME AND CORRELATION BETWEEN EXPERIMENTAL AND MODEL RESULTS
-
摘要: 介绍了一种新型结构体系密肋壁板轻框结构。针对该体系模态问题建立梁-板单元的空间有限元模型,参照振动台试验结果研究结构模型模态及其匹配性,并给出算例。Abstract: A new structure of multi-rib slab lightweight frame is introduced. A computational model with 3-D beam and plate element is set up according to the system model. Correlation between experimental and FEA model results is studied in the light of the test results from vibration tables, and an example is given.
