rectangular and circular concrete sections; steel pipes, tubes, and wide-flange

sections; and Section-Designer sections.

export as FEM, loads and properties are also exported. If you export as physical

objects, only geometrical line and surface entities will be created, but properties and

loads will not be exported.

� A new option to export a Perform3D Structure has been added. Most geometry,

material and section properties, restraints, diaphragm constraints, groups, loads, and

load cases are exported for frame and shell elements. Corresponding Perform3D

members are created depending on the properties and assignments present on the

individual SAP2000 members. Detailed hinge properties and other Perform3D-

specific features must be defined in Perform3D.

Notes:

� To be able to take advantage of the features of the newer CPU's, SAP2000 V14 will

not run on some of the older CPU's from Intel and AMD. A CPU that has SSE2 support

is now required

� SAPfire® Analytical Engine now includes a multi-threaded solver that can take

advantage of the newer multi-core CPUs.

� Support for Microsoft® Windows 2000 and Microsoft® Windows NT has been

discontinued. Microsoft® Windows XP without Service Pack 2 may cause unexpected

problems when running SAP2000 V14.

� With a 64 bit operating system, SAPfire® Analytical Engine can utilize more than 4 GB

of RAM, making it possible to more efficiently solve larger problems.

� The problem size that can be solved & the solution speed increases considerably with

more RAM. Vista requires more RAM than XP for the operating system itself.

� OpenGL graphics mode fully utilizes the hardware acceleration provided by a GPU &

dedicated graphics RAM.
