CHAPTER 1 GENERAL REQUIREMENTS
SECTION 101 - TITLE, PURPOSE AND SCOPE
These regulations shall be known as the National Structural Code of the Philippines 6th Edition 2010, may be cited as such and will be referred to herein as this code."
The purpose of this code is to provide minimum load requirements for the design of buildings and other structures and minimum standards and guidelines to safeguard life or limb, property and public welfare by regulating and controlling the design, construction, quality of materials pertaining to the structural aspects of all buildings and structures within this jurisdiction.
The provisions of this code shall apply to the construction, alteration, moving, demolition, repair, maintenance and use of any building or structure within this jurisdiction, except transmission towers and poles, hydraulic flood control structures, and indigeneous family dwellings.
Special structures such as but not limited to storage silos and liquid product tanks should be referred to special state of practice literature but shall refer to provisions of this code as a minimum wherever applicable.
Following are the different volumes of this code:
Volume I - Buildings, Towers and Other Vertical Structures
Volume II - Bridges
Volume III -Housing
Volume IV -Railways
Volume V-Ports and Harbors
For additions, alterations, maintenance, and change in use of buildings and structures, see Section 108.
Where, in any specific case, different sections of this code specify different materials, methods of construction or other requirements, the most restrictive provisions shall govern except in the case of single family dwellings. Where there is a conflict between a general requirement and a specific requirement, the specific requirement shall be applicable. Wherever in this code reference is made to an appendix, the provisions in the appendix shall not apply unless specifically adopted.
101.4 Alternative Systems
The provisions of this code are not intended to prevent the use of any material, alternate design or method of construction not specifically prescribed by this code, provided any alternate has been permitted and its use authorized by the building official.
Sponsors of any system of design or construction within the scope of this code, the adequacy of which had been shown by successful use and by analysis and test, but which does not conform to or is not covered by this code, shall have the right to present the data on which their design is based to the building official or to a board of examiners appointed by the building official. This board shall be composed of competent structural engineers and shall have authority to investigate the data so submitted, to require tests, and to formulate rules governing design and construction of such systems to meet the intent of this code. These rules, when approved and promulgated by the building official, shall be of the same force and effect as the provisions of this code.
SECTION 102 - DEFINITIONS
For the purpose of this code, certain terms, phrases, words and their derivatives shall be construed as specified in this chapter and elsewhere in this code where specific definitions are provided. Terms, phrases and words used in the singular include the plural and vice versa. Terms, phrases and words used in the masculine gender include the feminine and vice versa.
The following terms are defined for use in this chapter:
ADDITION is an extension or increase in floor area or height of a building or structure.
ALLOWABLE STRESS DESIGN is a method of proportioning structural members such that elastically computed stresses produced in the members by nominal loads do not exceed specified allowable stresses (also called WORKING STRESS DESIGN).
ALTER or ALTERATION is any change, addition or modification in construction or occupancy.
APPROVED as to materials and types of construction, refers to approval by the building official as the result of investigation and tests conducted by the building official, or by reason of accepted principles or tests by recognized authorities, technical or scientific organizations.
AUTHORITY HAVING JURISDICTION is the organization, political subdivision, office or individual charged with the responsibility of administering and enforcing the provisions of this code.
BUILDING is any structure usually enclosed by walls and a roof, constructed to provide support or shelter for an intended use or occupancy.
BUILDING, EXISTING, is a
