ADAPT-Builder 2015.0 Builder 2015 enables a new workflow using Patent-pending tributary load takedown technology combined with ADAPT's trusted 3D Finite Element solution. Our integrated column design approach uniquely offers design of columns for Tributary, Finite Element, or enveloped loads. Coupled with the industry's only single-model approach to combined global and single-level analysis and design, Builder helps you save time and effort. uick and simple load takedown using tributaries Size structural elements Columns Slabs Transfer elements Foundations Post-tensioning Wind and seismic forces Fully integrated frame action Incorporates effects of post-tensioning Same model for gravity and lateral analysis, each with own stiffness profile Post-tensioned floor systems Mild reinforced floor systems Beams Foundations (mat or isolated) Columns ADAPT-Builder is specifically designed for the rapid modeling of concrete structures and gives the option of adding prestressing or post-tensioning to any slab or beam member at any level. Directly import concrete building models from Revit Structure or CAD, or use your Builder model to generate a new Revit Structure model. Compatible with Revit Structure 2015.
