III. STRUCTURAL SYSTEMS <br />The structure is a two-story building. The building's structural system is as follows: <br />- First Floor - Crawl Space Flooding Level <br />o Concrete Grade Beams supported on piles. <br />o Concrete Slab over grades beam. <br />- Second Floor: <br />o Plywood. <br />o Wood Joist seated on top of the wall without any strap connector. <br />o Clay block wall unreinforced, interlocked by mortar. <br />- Roof: <br />o Wood Trusses over the wall, with wood collar ties. Notice there are not any <br />connectors between the wall and the wood truss. <br />o Clay tiles. <br />Performing the inspection visually was useful to determine spalling and cracking issues <br />on the concrete structure. Our office coordinated to perform some destructive and non- <br />destructive test to determine the capacity of the structural systems. Notice in this report <br />we are addressing the results of the test in Appendix B. <br />IV. STRUCTURAL EVALUATION <br />Building constructions and standards of the 1930's are considered deficient by today's <br />standards. This applies to this structure and other structures built in the 1930's. This <br />building does not comply with the current building code. The structure's roof connections <br />for wind uplift forces and for wind lateral resistance are non-existent. Moreover, <br />openings protection and CMU reinforcing is also non-existent. To bring this building into <br />compliance, it must undergo level III alteration of the Florida Building Code 2020 (7th <br />edition) for existing structures. This means that the building has to be strengthened to <br />comply with the current Florida Building Code. Which means that the roof connection tie <br />downs have to be implemented to strengthen the roof and lateral load structural <br />systems have to be installed, such as shear walls. Wall openings such as doors and <br />windows and the exterior CMU walls must be reinforced. All corners of the building <br />would need concrete columns. Hence, the foundations also must be strengthened to <br />resist such lateral loads. <br />According to the structural inspection we determined that the following areas need <br />repair: <br />• Several linear cracking on the walls (clay blocks unreinforced). <br />51 <br />Page 22 of 98 33 <br />
