The 40 Year Recertification Ordinance was initially adopted by the Miami-Dade County Commission in 1975. It was replaced in 2001 by the current law which adopts the Florida Building Code and continues the requirement that buildings in Miami-Dade County after 40 years (and every 10 years thereafter) be re certified by a registered Florida Engineer or Architect for structural and electrical safety. This Ordinance applies to all of unincorporated Miami-Dade County and the incorporated Cities within the County.

Important notice

The effective date for the 2007 Florida Building Code has been postponed to March 1, 2009.

This is to let you know that at the September 15, 2008 conference call meeting, the Florida Building Commission decided to postpone the effective date of the 2007 Florida Building Code from December 31, 2008 to March 1, 2009.

OES Wind Analysis is a wind analysis program that analyzes pressures of roofs, windows, walls, and components to create a calculation spreadsheet printable.

It will be released very soon and will definitely help structural engineers with wind structural calculations.

ASCE 7-05 has some changes. Among those changes, the ones related with wind load, live load and loading combination can be summarized as follow;

Wind Loads:

1. Clarified and expand the application of Method 1 – Simplified Method
2. Excluded torsionally sensitive buildings from using Method 1.
3. Modified the pressures for parapets and clarify their application for low-slope roofs
4. Added a definition for eave height and clarify footnote 8 of Figure 6-10.
5. Added provisions for freestanding walls and solid signs
6. Added provisions for canopies and free roofs

It is crucial that structural engineers recognize that strengthening assessment and design is infinitely more complex than new construction. Typically, challenges arise because of unknown factors associated with the structural state - such as continuity, load path, and material properties - as well as the size and locations of existing reinforcement or pre-stressing.
