ADAPT MODELER TUTORIAL

ADAPT-Modeler Examples

OVERVIEW

This compilation contains several typical examples of floor systems that have been modeled usingADAPT-Modeler. The first example (Shiraz Building) is the same used in the tutorial manual ofADAPT-Modeler.

In general, there is more than one way to define load paths for a given floor system. The optionspresented in the examples presented are viewed to be in line with common industry practice.

1.1 Example 1 - The Shiraz Building

This example is the two-way flat slab used for the tutorial in the previous chapter. Thecompleted model is contained in the Example1.DWG file included in the program CD-ROM.The model file is complete and ready to export data to ADAPT-PT. Below are sample planoutputs for the example.

1.2 Example 2 - The Prosperity Slab

This example is a two-way flat slab with irregular support layout, introduced in the PTIpublication Design Fundamentals of Post-Tensioned Concrete Floors. Drop caps and droppanels have been included at several locations, as well as a wide shallow beam at one edge ofthe slab. Figures 1.2-1 and 1.2-2 summarize the model geometry. On the following pages aresample output for the model.

1.3 Example 3 - Slab and Beam Parking Structure

This example illustrates a typical beam and slab parking deck. Sample outputs are includedbelow.

ADAPT MODELER EXAMPLES

Note, the slab region, including ramp area, has been modeled all on the same level. Thecutout in the slab region (between G9 and G10) represents the discontinuity at the ramp.

EX - 21

ADAPT MODELER EXAMPLES

Notice that the one-way slab was run so that only a small portion of the slab was covered.This was done with domain splitters as described in the Program and User Interface Manuals.

EX - 22

ADAPT MODELER EXAMPLES

Note, support lines along G6 through G10 are split into two support lines to reflect thediscontinuity due to the ramp. Other support lines are continuous across the structure.

ADAPT MODELER EXAMPLES

Note, splitters are used to define the design strips in the X-direction (two slab strips and onetransfer beam strip). The transfer beam loads must be adjusted in ADAPT-PT to reflect thetrue loading on the design strip (to include reactions of transverse beam). Splitters 1-4 arestrip splitters; 5-7 are domain splitters.

ADAPT MODELER EXAMPLES

Note, splitter 8 is used to delineate design strips at the ramp into two separate strips at eachgridline.

1.4 Example 4 - The Ramson Building, Irregular Two-way Slab

This example illustrates the versatility of using Modeler’s splitter and connector features toassign load paths in an irregular two-way slab. The complete DWG file (Example4.DWG)has been included with the software.
