Codes and Standards

the essential foundations of any building. These are the guidelines that designers strictly adhere to when it comes to their designs

Codes and Standards

These provide safeguards against anonymity in designs since these codes and standards are proven to be effective in their own respective fields of specialization.

National Building Code of the Philippines

to provide for all buildings and structures, a framework of minimum standards and requirements to regulate and control their location, site, design, quality of materials, construction, use, occupancy, and maintenance

Building Requirements

-All buildings or structures as well as accessory facilities shall conform in all respects to the principles of safe construction and must be suited to the purpose for which they are designed

National Structural Code of the Philippines

To provide minimum requirements for the design of buildings, towers, and other vertical 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 its jurisdiction.

FIVE GENERAL Design Requirements

strength requirement, serviceability requirement, structural analysis, foundation investigation, and design review.

strength requirement

vertical structures and all portions of it shall be designed and constructed to sustain, within the limitations of the code, all loads imposed in it i.e. dead loads, live loads.

Serviceability

how good the structure could be of use based on its purpose such that the structure maintains its usability once it is operational.

serviceability requirement

provides that structural systems and its structural members shall be designed to have adequate stiffness to limit deflections, lateral drifts, vibrations, or any other deformations that adversely affect the intended use and performance of buildings, towers, and other vertical structures.

structural analysis

applied for the structure, system or method of construction, shall be based on a rational analysis in accordance with well-established principles of mechanics that take into account equilibrium, general stability, geometric compatibility, and both short-term and long-term material properties.

Structural Analysis

Structural Analysis
