FLEXURAL STRIUCTURE SYSTEMS B E A M S including SAP2000 Prof. Wolfgang Schueller
For SAP2000 problem solutions refer to “Wolfgang Schueller: Building Support Structures – examples model files”: https://wiki.csiamerica.com/display/sap2000/Wolfgang+Schueller%3A+Building+Su pport+Structures+- If you do not have the SAP2000 program get it from CSI. Students should request technical support from their professors, who can contact CSI if necessary, to obtain the latest limited capacity (100 nodes) student version demo for SAP2000; CSI does not provide technical support directly to students. The reader may also be interested in the Eval uation version of SAP2000; there is no capacity limitation, but one cannot print or export/import from it and it cannot be read in the commercial version.

FLEXURAL STRUCTURE SYSTEMS B E A M S There are infinitely many types of beams. They may be hidden or exposed; they may form rigid solid members, truss beams, or flexible cable beams. They may be part of a repetitive framing grid (e.g., parallel or two-way joist systems) or represent individual members. They may support ordinary floor and roof structures or span a stadium; they may form a stair, a bridge, or bridge-type buildings that span space; they distinguish themselves in material, construction, and shape. Beams may be not only common beams, but may be spatial members, such as folded plate and shell beams (e.g., corrugated sections), or space trusses. The longitudinal profile of beams may be shaped in funicular form in response to a particular force action, which is usually gravity loading; that is, the beam shape matches the shape of the moment diagram to achieve constant maximum stresses.
BEAMSmay not only be the common, • planar beams • spatial beams (e.g. folded plate, shell beams , corrugated sections • space trusses. They may be not only the typical rigid beams but may be flexible beams such as • cable beams. The longitudinal profile of beams may be shaped as a funicular form in response to a particular force action, which is usually gravity loading; that is, the beam shape matches the shape of the moment diagram to achieve constant maximum stresses.
Beams may be part of a repetitive grid (e.g. parallel or two-way joist system) or may represent individual members; they may support ordinary floor and roof structures or span a stadium; they may form a stair, a bridge, or an entire building. In other words, there is no limit to the application of the beam principle. The following slides represent: 1.Case studies as described above presented in a casual fashion 2.
