What are the levels of SHM defined in this code?

Level I (Damage Detection), Level II (Damage Localization), Level III (Damage Quantification), and Level IV (Prognosis/Remaining Life Prediction) (Clause 4.2, Table 1).

Does this code mandate SHM for all buildings?

No, it provides guidelines. The decision to implement SHM depends on the building's importance, age, condition, and risk exposure (Clause 1.2).

What is the difference between SHM and NDT?

SHM is typically a continuous or periodic long-term process using installed sensors, while NDT (Non-Destructive Testing) usually involves one-time, localized tests to find flaws or assess material properties (Clause 3.10 & 3.17).

Structural Health Monitoring of Existing Buildings - Guidelines

This standard provides guidelines for the structural health monitoring (SHM) of existing buildings to assess their condition and performance. It covers the principles, processes, monitoring techniques, and data management required to ensure structural safety and predict remaining service life, particularly for important or aging structures.

Provides guidelines for implementing structural health monitoring systems for existing buildings.

Quick Reference Values

SHM Level IDamage Detection - Identifies if damage has occurred.

SHM Level IIDamage Localization - Identifies if damage has occurred and where.

SHM Level IIIDamage Quantification - Quantifies the severity of the damage.

SHM Level IVPrognosis - Predicts the remaining service life of the structure.

Practical Notes

The selection of sensor types and their placement is critical and must be tailored to the specific building, expected damage patterns, and monitoring goals.

SHM complements, but does not replace, traditional visual inspections and non-destructive testing (NDT); it provides continuous quantitative data.

A significant challenge in SHM is differentiating between sensor readings caused by environmental/operational changes (like temperature) and those indicating actual structural damage.
