FEMA P55 Coastal Construction Manual, Fourth Edition - Mad Cad

Volume II PRE-DESIGN CONSIDERATIONS 7
COASTAL CONSTRUCTION MANUAL
Figure 7-1.
Design framework for
a successful building,
incorporating cost, risk
tolerance, use, location,
materials, and hazard
resistance
Volume II contains many design equations, but they do not cover all of the design calculations that are
necessary and are provided only as examples.
7.2 Design Requirements
The minimum design requirements for loads, materials, and material resistances for a given building
design are normally specified in the locally adopted building code. Nothing in this Manual is intended to
recommend the use of materials or systems outside the uses permitted in building code requirements. The
loads used in this Manual are based on ASCE 7-10, which is the reference load standard in model building
codes. Material and material resistance requirements cited in this Manual are based on the minimum
requirements of applicable building codes. However, designers are encouraged throughout the Manual to
seek out information on loads and materials that exceed the minimum requirements of the building code.
Other sources of information for loads and materials are also provided.
7.3 Determining the Natural Hazard Risk
Assessing risk to coastal buildings and building sites requires identifying or delineating hazardous areas and
considering the following factors:
Types of hazards known to affect a region
Geographic variations in hazard occurrence and severity
Methods and assumptions underlying existing hazard identification maps or products
