SCE Saudi Building Code 1

Question 1

The Saudi Building Code (SBC) is primarily based on which international model codes?

Accepted Answer

International Building Code (IBC) and ACI/ASCE standards with Saudi-specific modifications

Answer

The SBC is largely adapted from the International Building Code (IBC) family and American standards (ACI 318, ASCE 7, AISC 360) with modifications for Saudi climate, soil conditions, and Islamic requirements.

Question 2

SBC 301 (Structural - Loading and Forces) specifies the minimum live load for residential buildings as:

Accepted Answer

2.0 kN/m²

Answer

SBC 301 specifies a minimum live load of 2.0 kN/m² (approximately 40 psf) for residential occupancies, consistent with international standards and typical Saudi housing construction practices.

Question 3

According to SBC, what is the minimum concrete cover for reinforcement in foundations exposed to soil?

Accepted Answer

75mm

Answer

SBC requires 75mm minimum cover for concrete cast against and permanently in contact with ground, providing adequate protection against soil moisture, chemicals (especially sulphates), and potential reinforcement corrosion.

Question 4

The Saudi Building Code classifies occupancy types primarily to:

Accepted Answer

Determine fire safety requirements, structural loads, and means of egress

Answer

Occupancy classification determines fire protection requirements (sprinklers, fire ratings), structural design loads, egress requirements (exit widths, travel distances), and ventilation standards.

Question 5

SBC seismic design requirements divide Saudi Arabia into seismic zones based on:

Accepted Answer

Mapped seismic hazard with specific ground motion parameters for each region

Answer

The SBC uses seismic hazard maps showing spectral accelerations (Ss and S1) for different locations. Western Saudi Arabia (Hejaz) and southern regions near the Red Sea rift have higher seismic hazard.
