NEC - SE - CG code (Minimum loads):
The NECSE-CG provides a general framework for structural designer. Loads to be considered in the calculation and design of all types of structures are:
• permanent loads (minimum dead loads in particular).
• variable loads (live loads, wind and hail).
They will be complemented by accidental loads are seismic loads (in new construction and rehabilitation), subject to the NEC-SE-DS and NEC-SE-RE standards. Shall not be taken into account:
• temporary loads due to the construction process,
• dynamic wind loads,
• loads or accelerations due to moving vehicles, explosion, sinking foundations and others due to natural phenomena.

NEC - SE - MP code (Masonry):
This chapter presents criteria and minimum requirements for the design and construction of structures of unreinforced masonry, reinforced masonry and confined masonry, up to 4 floors. The requirements of this chapter are aimed at achieving an appropriate behavior of structural masonry buildings in low load conditions defined in the NEC-GCSE. Structures able to withstand all expected internal stresses (compression, tension, bending, torsion, etc. and combinations thereof), to deform and move permissible way to design.
Units: units will be used S.I. according to ISO 1000 Standard.

NEC - SE - HM code (Structural concrete):
The structural elements of reinforced concrete must comply with the latest specifications of the ACI-318 code. The seismic design will be in accordance with the NEC-SE-DS standard, indicating except Chapter 21 of ACI-318 code (Earthquake Resistant Structures). The provisions of this chapter apply to the design of buildings where seismic loads resistant system consists of:
• special frames,
• reinforced concrete structural walls.
This NEC-SE-HM is for reinforced concrete. For other types of concrete, not specified in this standard, it should refer to the following chapters of the ACI 318:
• Chapter 16 (Precast concrete)
• Chapter 18 (Prestressed Concrete)
• Chapter 22 (Single structural concrete)
International system of units (SI) according to the ISO 1000 standard are used.

NEC - SE - AC code (Structural steel):
These provisions consider that steel structures will be designed, manufactured and assembled using hot rolled profiles or armed assembled by means of welded plates.
These provisions shall apply where the reduction coefficient of seismic response R, specified in the NEC-SE-DS of these standards is greater than 3. The structural steel systems designed to higher-R 3 is expected to dissipate energy from movements design ground through inelastic deformations of the structure. For those cases where the rate of reduction of seismic response, R, is equal to or less than 3, no need to meet the requirements in these provisions, except for special systems of columns projecting where it must meet the requirements included in these systems.
The provisions in this chapter are based on the provisions presented in the ANSI / AISC 341-05 documents, ANSI / AISC 341-10 (Seismic Provisions for Structural Steel Buildings), 358-05 (prequalified Connections for Special and Intermediate Steel Moment Frames for Seismic Applications) and FEMA 350 Recommended Seismic Design Criteria for New Steel Moment Frame Buildings). These documents reflect the most current relative to the seismic performance of structural steel buildings in the United States knowledge.
Specifications and codes referenced in these provisions shall be those listed in Section A2 of the ANSI / AISC 360-10.
