Two- and three-dimensional beam/connector elements are formulated, tested, and evaluated. The dome cap is modeled with I-DEAS, and the modeling procedures are briefly discussed. Four series of beam/connector dome cap models are created and analyzed: (1) models with the nailed joints at bracing points (rigid link h=0), (2) models with the nailed joints at bracing points (h>0), (3) models with 16 nailed joints per beam element (h=0), and (4) models with 16 nailed joints per beam element (h>0). Their results are compared with the dome cap models with the truss bracings. Finally, conclusions and recommendations for future research are presented.x, 229 leavesBTDapplication/pdfenIn CopyrightLD5655.V855 1992.T827DomesGirders -- TestingThree-dimensional display systemsThesishttp://scholar.lib.vt.edu/theses/available/etd-09052009-040556/
