Structural design of brick dome of Millet Vinegar Museum
The entrance hall of Millet Vinegar Museum in Zibo city,Shandong Province adopts a brick dome structure.The finite element analysis software was used to calculate the brick dome structure,and the structural schemes of different bus shapes were compared and selected.The influence of three arched door holes set at the bottom of the structure on the internal force of the structure was analyzed,and the limit equilibrium method was used to check the structure.The main natural vibration modes of the dome structure and the dynamic characteristics under earthquake action were obtained.The force of the structure in different construction stages was analyzed,and an accurate bricking model was established to guide and control the whole construction process.The brick arrangement method of dome structure was introduced in detail,and the traditional brick laying process was improved to achieve the ingenious combination of structural stress and architectural aesthetics.The results show that the tensile stress concentration occurs at the top of the door at the bottom of the structure under static force,and the circumferential tensile stress is formed between the tops of the doors.Under the action of earthquake,the tensile stress value in the middle of the structure and the bottom of the unopened side is small and evenly distributed,and the tensile stress of the structure near the bottom of the door increases significantly.
