be added without sequential staging as present construction practices require further all components of the terraced structured land joint and assembly can be built in factories easily transported to the job site and assembled without training or extensive knowledge of construction trades construction time is greatly reduced weather or seasonal considerations would not dictate construction scheduling with reference to drawing fig1 13b a terraced structured land joint and assembly for structured land is presented an embodiment of he land joint and assembly includes a plurality of ball joints 20 a having outer surfaces each ball joint having a plurality of monolithic mortises 74 of even diameter disposed on the ball joint outer surface 26 at predetermined locations and angles each such monolithic mortise having a monolithic tension member 70 of predetermined diameter centered in each mortise 74 and extending orthogonally therefrom for a predetermined length along a longitudinal axis and having a swelled end portion 72 fig6 9 and 9 a a second embodiment of the land joint and assembly further includes a plurality of ball joints 20 b having outer surfaces each ball joint having a plurality of monolithic tenons 24 disposed on the ball joint outer surface 26 at predetermined locations and angles each such monolithic node having a monolithic tension member 70 of predetermined diameter centered on the tenon 24 and extending orthogonally therefrom for a predetermined length along a longitudinal axis and having a swelled end portion 72 fig7 8 9 and 9 a an embodiment of the land joint and assembly further includes a a plurality of compression members 40 of predetermined length defining a uniform compression member cross sectional area and uniform compression member interior volume 44 for receiving and housing at least one tension member 50 and having two compression ends sized.
