Which of the following approaches would be best for creating a risk-based inspection and testing...

A risk-based inspection and testing strategy for a high-rise structure in a seismic zone must be designed specifically to account for the unique structural integrity challenges posed by seismic activity. A tailored approach ensures that construction quality management aligns with best practices in seismic resilience.

Seismic Risk Assessment and Categorization

The structure should be classified according to its seismic risk category based on national and international standards such as DOE-STD-1020-2016 and ANSI/ANS-2.26-2004 (R2010)​.

Identifying structural components most vulnerable to seismic forces helps determine inspection priorities.

Enhanced Inspection and Testing of Structural Components

Special attention should be given to foundation stability, reinforced concrete elements, and load-bearing steel structures, ensuring they meet seismic design specifications​.

Use non-destructive testing (NDT) methods to assess material integrity and detect internal weaknesses.

Structural Health Monitoring (SHM) Integration

Implementing real-time monitoring systems, such as accelerometers and strain gauges, provides continuous data on the structure’s response to seismic activity​.

Periodic structural health assessments should be conducted to evaluate fatigue and stress accumulation.

Quality Assurance for Seismic-Resistant Materials and Design Features

Material specifications should be aligned with seismic performance standards, ensuring high ductility and energy absorption capacity​.

Reinforced concrete and steel connections should undergo stringent inspection protocols.

Compliance with Seismic Codes and Regulations

Adherence to FEMA P-58, ASCE 7-16, and AISC 341-16 ensures that design and inspection practices are aligned with modern seismic engineering principles​.

Periodic audits should verify that construction phases comply with these regulatory standards.

A. Adapt inspection strategies used in non-seismic zones with adjustments for seismic events – This does not fully address the unique risks of seismic activity. A tailored seismic approach is necessary.

C. Balance the frequency of inspections with project timelines to minimize delays – While efficiency is important, inspections in seismic zones must be thorough and prioritized over project speed.

D. Increase inspections only if there are signs of seismic activity during construction – A proactive, rather than reactive, approach is essential for ensuring structural resilience.
