Abstract: The present study was undertaken to optimize the shear strength of the regular hexagonal, triangle and square lattice structure which can be used in the exterior beam column joint. Here, shear strength and shear stress values are compared to the normal exterior beam column joint which is detailed as per IS13920:2016 and IS456:2000. Optimization of the shape of the unit cell was carried out to obtain maximum shear stress. The optimum shear stress of lattice unit cell is found by varying the thickness and length of lower limit and upper limit. The unit cell of 10mm is taken as a maximum length and the thickness is varied for various shapes. Genetic Algorithm which is a non – traditional optimization is used for optimizing the shear stress.
