Study on static and anti-lunar seismic performance of mortise and tenon block masonry structures
A design scheme of lunar base using the mortise and tenon block masonry structure was introduced,and a rigid-flexible hybrid construction method was proposed.The mechanical performance of the structure was studied through static analysis and dynamic time-history analysis.In the static analysis,the influence of different mortise and tenon forms and friction coefficients at the mortise and tenon nodes on the structural force was studied.In the dynamic time-history analysis,the stress and displacement responses of the structure under lunar seismic action were considered.The results show that the use of oblique mortise and tenon structures has greater bearing capacity and smaller deformation,and increasing the friction coefficient can also improve the stiffness and bearing capacity of the structure.Using an oblique mortise and tenon form can significantly reduce the structural response,and improve the safety and reliability of the structure,and with the increase of the friction coefficient,the dynamic response of the structure decreases.
