2 Floor PanelsGeneralThere are a number of reasonsfor choosing autoclaved aerat-ed concrete floors. Considerthe low weight, for influences the size andweight of the foundation, sincea traditional floor weighs threetimes as much as its fire-resistant characteristicsfor Aercon are , the Aercon floor panelshave superior sound and ther-mal characteristics inherent toAERCON distinct advantage ofusing Aercon floor panels isthe speed of installation. Afloor area up to 40 ft2is easilyinstalled with one crane liftutilizing a well-trained panels are supplied onthe basis of Strength Class AC4and AC6. The maximum panellength is 20'-0". The standardpanel width is 2'-0".

3 A nominalpanel thickness of 8", 10" or 12"is available depending on theloading and span require-ments. Reinforcing is placed in key joints between panels for continuity and diaphragm - Structural Design06/03 / VII-4 Panel SystemFloor panels are tailor length, thickness andreinforcement are determinedbased on the building require-ments and specifications. Thestandard panel width is 2'-0".See the Overview Section forpanel profile Cutting and OpeningsAll panels may be cut and maycontain openings throughoutthe panel. However, the size,location and type of cut or open-ing should be coordinated withAERCON prior to the designphase to avoid any unnecessaryfield modifications.

4 The reason for this is that everyopening, notch or cut (round,rectangular, diagonal) causesadditional stress on the areaaround the potential cut.

The following typical loads maybe used for calculating the panelthickness. However, all panels aredesigned based on the projectrequirements, as specified by theDesign Professional.

This graph may beused for the preliminary deter-mination of the thicknessrequired for a particularproject. Since floor panels areuniquely designed for a project,the maximum span for anindividual panel may deviatefrom the graphical allowable deflection ofAERCON floor panels, due tothe total load, is L/240.

Aercon roof panels can beinstalled on a slope or thermal effects, within thebuilding, from the summer andwinter temperatures are mini-mized.

7 Similar to Aercon floorpanels, Aercon roof panelsweigh less than other concreteroof systems. Therefore, areduction in the size and weightof the building foundation sys-tem may be distinct advantage ofusing Aercon roof panels is thespeed of installation. A roof areaup to 40 ft2 is easily installed withone crane lift utilizing a well-trained erection crew.
