ADAPT Promotes Integration with General Analysis Programs
(e.g., ETABS)

To build on the industry's broader adoption of general purpose building analysis programs and to streamline the design process, ADAPT has launched its Open Platform Strategy. This integration strategy gives ADAPT clients the flexibility of using the general purpose programs they are already comfortable with in conjunction with their ADAPT slab design solution, without having to manually transfer data.

For example, in the next release of ADAPT-Floor Pro (v1.50), users can seamlessly import solutions from ETABS and combine them with the gravity loads and prestressing, if any, for a complete code check and design of the building's floor system. Similar integration with other major programs is available through the "lateral data exchange" filter implemented in ADAPT-Floor-Pro.


ADAPT Elected to PTI Board

Gerard McGuire, EVP for Business Development at ADAPT, was unanimously elected to serve as the new Affiliate Member Representative to the Post-Tensioning Institute (PTI) Board of Directors for a two-year term starting Jan. 2005. The election took place during the PTI Board of Directors meeting in Phoenix, AZ in October 2004. "We are very pleased with Gerard's appointment to the PTI Board of Directors as it allows ADAPT to contribute to the development of the post-tensioning market," adds Dr. Bijan O. Aalami, CEO of ADAPT.


ADAPT Joins ACI Committees

Mr. McGuire has also been accepted to serve as a committee member on two American Concrete International (ACI) Committees - ACI 423 Prestressed Concrete and ACI 362 Parking Structures.


ADAPT Staff Publishes Research Results on Shrinkage

ACI's Concrete International published Snezana Ristanovic's paper "Predicting Drying Shrinkage of Concrete" in its August 2004 issue. Ms. Ristanovic, a product manager at ADAPT, also presented the results of her research to ACI's Committee 209 - Creep and Shrinkage, at the recently held annual ACI Convention in San Francisco, CA. She was subsequently asked to submit the paper "Sensitivity of Models for Shrinkage Predictions" for publication in an upcoming ACI Special Publication to be released in March/April 2005.

Snezana is a key contributor to ADAPT's software development team and is also working on the next generation ADAPT-Builder Platform that will incorporate time-dependent analysis (creep and shrinkage).

Software Updates

NEW RELEASE - ADAPT-PT, v7.00

In December 2004, ADAPT released a new version of ADAPT-PT, version 7.00. Most significantly, this new version adds ACI 318-2002/IBC 2003 to ACI 318-1999, BS8110, and Canadian as selectable design code options. In addition to the incorporation of the latest design codes, clients will find enhancements to the program.


PROGRAM UPDATE - WINDOWS XP

For those users of Windows XP, we suggest you install the latest HASP drivers to provide smooth operation of your program.

Please download and install the HASP_User_Setup.zip from the Aladdin site at:

EXPECTED RELEASE - ADAPT-Builder v1.50

ADAPT is planning the next release of ADAPT-Builder Platform (changes will apply to ADAPT-Builder Platform solutions ADAPT-Floor Pro, -MAT and -SOG), version 1.50, in the first quarter of 2005. The highlight of this latest release will be the implementation of ADAPT's Open Platform Strategy through its integration interface with ETABS. This release will also be packed with performance enhancing improvements and functionality for modeling, meshing, tendon editing, and report generation operations.


BETA RELEASE - ADAPT-Builder v2.00 beta

In November 2004, ADAPT released a beta version of its next generation ADAPT-Builder Platform, version 2.00, for testing by clients. This new version of ADAPT-Builder delivers unprecedented improvements to the overall floor system design process with its advanced rebar and tendon graphical output and drafting capabilities.

Unlike other slab design programs that simply output their designed reinforcement as un-editable images, the reinforcement designed using one of the ADAPT-Builder design programs, e.g. ADAPT-Floor Pro, is presented to the user as fully editable components on the screen. Users can then easily modify the designed reinforcement, possibly adjusting orientation or adding additional bars, as needed. The final design and reinforcement layout is then ready for seamless export into AutoCAD. Beta users are already saving considerable time and reducing errors by automatically generating their structural rebar and post-tensioning drawings from their floor system models in ADAPT-Builder programs.

Technical Note

Impact of ACI 318-2002 and 2005 for PT Design

A change implemented in ACI-318-02, and being carried to the 2005 Code issue has a significant, but beneficial impact on the economy of post-tensioned buildings. For the same building layout and occupancy, in most instances the new code requires less nonprestressed rebar. The following describes the change:
    (i) For strength check, the 1999 code required a load combination of (1.4xDL + 1.7xLL + 1xSeconday Moments). The new code has reduced the dead load coefficient to 1.2 and the live load factor to 1.6. This significantly reduces the design moment, and thereby the required reinforcement.
There are other changes in the code that affect the PT design. While these must also be accounted for in your design, their impact is not as significant. The latest version of ADAPT-PT, version 7.00, designs according to ACI 318-2002.


ADAPT releases 3 new general Technical Notes:
  • Prestressing Losses and Elongation Calculation (T9-04)
  • Design of post-tensioned members in bending using ACI 318-02 - simplified procedure (TN 179)
  • Strain compatibility for design of post-tensioned members in bending, using ACI 318-02 (TN 178)

In addition to these generally applicable Technical Notes, ADAPT continuously develops new, software-specific notes that help our clients maximize their utilization of our design solutions. To access the latest list of software-specific notes, please go to the product update area for your program.

Project Highlight

Moody Gardens® Hotel Expansion

ADAPT-PT design software of choice for complex hotel project

Location: Galveston Island, Houston
Owner: Moody Gardens®
Engineer of Record: Walter P. Moore Engineers + Consultants
Project Cost: $115 million

Project Description
Moody Gardens®, known as one of the top tier entertainment complexes in the southern United States, features three signature pyramids (with aquarium, museum, and tropical rainforest themes), an IMAX theater and an artificial white-sand beach which are surrounded by a 9-story hotel with an adjoining convention center and has become one of the Houston area's favorite tourist attractions, drawing more than 2 million visitors annually to Galveston Island.

The new hotel expansion was constructed to keep up with the ever growing needs of the rapidly expanding Moody Gardens® complex and was part of an overall $115 million Phase V expansion. Phase V included the new hotel tower, an expansion of the existing hotel restaurant, an expansion and renovation of the convention center, a new 1,000 car cast-in-place post-tensioned parking garage, new maintenance and warehouse structures, expanded utility infrastructure and other campus improvements.

The Phase V addition to the hotel completed in Dec 2003, provided a new 7-story plus basement, 125 room expansion to the existing 300 room 9-story building. The new structure was designed for two floors of future expansion to eventually match the existing hotel When the complex column layout and small floor to floor heights required to match the existing structure (typically 9'-8") were considered for the structural system, a post-tensioned slab was the obvious choice for Walter P. Moore, the structural engineers for all work at the Moody campus. The irregular column layout was driven by the saw tooth profile of the building designed to provide scenic picture windows and balconies that overlook the West Bay just off the Gulf of Mexico. The typical elevated structure of the hotel typically consists of 8" two-way post-tensioned flat plate floors with 14"x24" concrete columns and 12" shear walls at the stair and elevator cores.

Walter P. Moore chose ADAPT-PT to design the complex post-tensioned flat slab. Each level was divided up and modeled using the Equivalent Frame Method, most of which were not linear and had to bend or split to follow the irregular column pattern. ADAPT-PT was well suited to model the design frames that were varying in span, width, and load along the length of the strips. Even with the irregular column layout, ADAPT-PT could be used to model the frames and easily determine the required post-tensioning and mild reinforcement.
