To be acceptable under this code, every certificate of approval shall be made by an approved agency. Placement of prefabricated assemblies at the building site shall be inspected to determine compliance with this code. If continuous inspection is required for certain materials where construction takes place on the site, it shall also be required where the same materials are used in prefabricated construction. In Seismic Zone 4, welded, fully restrained connections between the primary members of ordinary moment frames and special moment-resisting frames shall be tested by nondestructive methods for compliance with approved standards and job specifications.
This testing shall be a part of the structural inspection requirements of Section A program for this testing shall be established by the person responsible for structural design and as shown on plans and specifications. As a minimum, the testing program shall inclt,lde the following: For partial penetration groove welds when used in column splices, with an effective throat less than 20 mm thick, nondestructive testing is not required; for this welding, continuous structural inspection is required.
Any material discontinuities shall be accepted or rejected on the basis of the defect rating in accordance with the larger reflector criteria of approved national standards. The structural engineer may accept or require in situ non-destructive testing of concrete or other materials and assemblies to supplement or replace conventional tests. When approved, the nondestructive testing rate for an individual welder or welding operator may be reduced to 25 percent, provided the reject rate is demonstrated to be 5 percent or less of the welds tested for the welder or welding operator.
National Structural Code of the Philippines(NSCP), Volume 1, Fourth Edition
A sampling of at least 40 completed welds for a job shall be made for SlIch reduction evaluation. Reject rate is defined as the number of welds containing rejectable defects divided by the number of welds completed For evaluating the reject rate of continuous welds over mm in length where the effective throat thickness is 25 mm or less, each mm increment or fractioll thereof shall be considered as one weld.
For evaluating the reject rate on 1. When so designated by the structural engineer, or 4. When such observation is specifically required by the building official. The owner shall employ the engineer responsible for the structural design, or another engineer designated by the engineer responsible for the structural design, to perform structural observation as defined in Section Observed deficiencies shall be reported in writing to the , owner's representative, structural inspector, contractor and the building official.
The structural observer shall submit to the building official a written statement that the site visits have been made and identifying any reported deficiencies that, to the best of the structural observer's knowledge, have not been resolved.
Any change in the use or occupancy of any existing building or structure shall comply with the provisions of Sections To determine compliance with this subsection, the building official may cause a structure to be re-inspected.
The structural observations shall be performed at the construction stages prescribed by the inspection program prepared as required by Section Buildings and structures to which additions, alterations or repairs are made shall comply with all the requirements of this code for new facilities except as specifically provided in this section.
It shall be the duty of the person doing the work authorized by the permit to notify the structural observer that the described construction stages have been reached, and to provide access to and means for observing the components of the structural system. Additions, alterations or repairs may be made to any building or structure without requiring the existing building or structure to comply with all the requirements of this code, provided the addition, alteration or repair conforms to that required for a new building or structure.
Additions or alterations shall not be made to an existing building or structure that will cause the existing building or structure to become unsafe. An unsafe condition shall be deemed to have been created if an addition or alteration will cause any structural element of the existing building or structure to resist loads in excess of their capacity or cause a reduction of their load carrying capacity.
Additions or alterations shall not be made to an existing building or structure when such existing building or structure is not in full compliance with the provisions of this code except when such addition or alteration will result in the existing building or structure being no more hazardous based on structural safety, than before such additions or alterations are undertaken.
The capacity of existing structural elements required to resist forces is not reduced, 2. New or relocated nonstructural elements are detailed and connected to existing or new structural elements as required by these regulations.
Alterations or repairs to an existing building or structure that are nonstructural and do not adversely affect any structural member or any part of the building or structure having required fire resistance may be made with the same materials of which the building or structure is constructed.
Repairs, alterations and additions necessary for the preservation, restoration, rehabilitation or continued use of a building or structure may be made without conformance to all the requirements of this code when authorized by the building official, provided: 1. Any structurally unsafe conditions are corrected.
The restored building or structure will be no more hazardous based on life safety than the existing building. Except as specified in Section A grading permit is not required for the following: 1. No change shall be made in the character of occupancies or use of any building unless the new or proposed use is less hazardous, based on life safety than the existing use. A change in use or occupancy of any building shall be allowed 0!
Alterations to the existing building shall be permitted to satisfy this requirement. When approved by the building official, grading in an isolated, self-contained area if there is no danger to private or public property. An excavation below finished grade for basements and footings of a building, retaining wall or other structure authorized by a valid building permit.

Specifications shall contain information covering construction and material requirements. Plans shall be drawn to scale upon substantial paper or cloth and shall be of sufficient clarity to indicate the nature and extent of the work proposed and show in detail that they will conform to the provisions of this code and all relevant laws, ordinances, rules and regulations.
The first sheet of each set of plans shall give location of the work, the name and 5.
General vicinity map ofthe proposed site. It was also shown that the data could be used in generating wind directionality factors. A similar work presented was by Elliott et al . Also cited was the recording of wind speeds in Naga City during the passing of Typhoon Unding in November , also freely available from the Typhoon Weather and other wind- and typhoon-related information in the Philippines were shown to be available from various other websites.
Some of these possible improvements were also discussed see next chapter. The idea that one single group could coordinate activities of all groups involved in developing these hazard maps was also suggested. Collaboration, and harmonization of documents and data between engineers and researchers from other fields were also promoted.

For a given direction of loading, the element-story shear ratio is the ratio of the design story shear in the most heavily loaded single element divided by the total design story shear.
CNW and CNL denote net pressures contributions from top and bottom surfaces for windward and leeward half of roof surfaces, respectively.
Diaphragms shall be considered flexible for the purposes of distribution of story shear and torsional moment when the maximum lateral deformation of the diaphragm is more than two times the average story drift of the associated story.
Maximum modal contributions are combined in a statistical manner to obtain an approximate total structural response.
