California Existing Building Code 2019 > 3A Provisions for All Compliance Methods > 303A Structural Design Loads and Evaluation and Design Procedures > 303A.3 Additions, Alterations, Repairs and Seismic Retrofit to Existing Buildings or Structures > 303A.3.4 Performance Objectives of Performance-Based Methods
JUMP TO FULL CODE CHAPTER
Except for the modifications as set forth in Sections 303A.3.4 and 303A.3.5, all additions, alterations, repairs and seismic retrofit to existing structures or portions thereof shall be permitted to be designed in accordance with the provisions of ASCE 41. When load combinations which do not include seismic forces are required, the new building code provisions of this code shall be applicable. Required building performance objectives under ASCE 41 shall be as follows:

303A.3.4.1 For General Acute Care Hospital Buildings Along With All Structures Required for Their Continuous Operation or Access/Egress:

  1. Immediate Occupancy (IO) Structural Performance Level (S-1) as defined in Section 2.3.1.1 at Basic Safety Earthquake 1N (BSE-1N) Seismic Hazard Level; and
  2. Life Safety (LS) Structural Performance Level (S-3) as defined in Section 2.3.1.3 at Basic Safety Earthquake 2N (BSE-2N) Seismic Hazard Level; and
  3. The nonstructural components shall satisfy the requirements of this code for new construction.
    Exception: Performance objectives for upgrading nonconforming hospital buildings to SPC-4D and for incidental or minor alterations or repairs of SPC-4D buildings shall be in accordance with Section 303A.3.4.5 of this code.

303A.3.4.2 For Incidental and Minor Additions, Alterations or Repairs of Pre-1973 Hospital Buildings Which Will Not Be Used for General Acute Care Services After January 1, 2030:

  1. Life Safety Structural Performance (S-3) Level as defined in ASCE 41 Section 2.3.1.3 at the Basic Safety Earthquake 1E (BSE-1E) Seismic Hazard Level; and
  2. Collapse Prevention (CP) Building Performance Level (5-D) in accordance with Section 2.3.3.4 at the Basic Safety Earthquake 2E (BSE-2E) Seismic Hazard Level; and
  3. The nonstructural components shall satisfy the requirements of Position Retention Nonstructural Performance Level (N-B) in accordance with ASCE 41 Section 2.3.2.2 at BSE-1E Seismic Hazard Level.

303A.3.4.3 All Other Hospital Buildings:

  1. Operational Building Performance Level of (1-A) as defined in Section 2.3.3.1 at Basic Safety Earthquake 1N (BSE-1N) Seismic Hazard Level; and
  2. Life Safety (LS) Building Performance Level (S-3) as defined in Section 2.3.1.3 at Basic Safety Earthquake 2N (BSE-2N) Seismic Hazard Level.

303A.3.4.4 SPC 2 Using ASCE 41

Structures shall be considered to comply with SPC 2 requirements of Table 2.5.3, Chapter 6 of the California Administrative Code, when all of the following are satisfied:
  1. Life Safety Structural Performance Level (S-3) in accordance with Section 2.3.1.3 of ASCE 41 at BSE-1E; and
  2. Items identified in Chapter 6, Article 10 of the California Administrative Code satisfying the requirements of Position Retention nonstructural Performance Level (N-B) in accordance with Section 2.3.2.2 at BSE-1E.

303A.3.4.5 SPC-4D Using ASCE 41

Structures shall be deemed to comply with the SPC-4D requirements of Table 2.5.3, Chapter 6 of the California Administrative Code, when all of the following are satisfied:
  1. Damage control Structural Performance Level (S-2) in accordance with Section 2.3.1.2.1 of ASCE 41 at BSE-1E; and
  2. Collapse Prevention Structural Performance Level (S-5) in accordance with Section 2.3.1.5 of ASCE 41 at BSE-2E; and
  3. Items identified in Chapter 6, Article 10 of the California Administrative Code satisfy the requirements of Position Retention Nonstructural Performance Level (N-B) in accordance with Section 2.3.2.2 at BSE-1E.
Exception: ASCE 41-13 ยง 7.2.13.2 Separation
Exemptions: Add the following exemption:
  1. Seismic separation is deemed to comply with SPC-4D requirements and a pounding analysis is not required where either A) or B) apply:
    1. The adjacent building was constructed using the 1989 or later edition of the California Building Code.
    2. The adjacent building meets the SPC building separation requirements in accordance with the California Administrative Code (CAC), Chapter 6, Section 3.4 and all the following are met:
      1. Where the structural resisting system of the adjacent building is different, the mass of the more flexible building is no greater than 50 percent of the mass of the stiffer building.
      2. The adjacent building does not have any of the following structural deficiencies as defined in CAC, Chapter 6, Article 3:
        1. Load path (3.1)
        2. Weak story (3.3.1)
        3. Soft story (3.3.2)
        4. Vertical discontinuity (3.3.5) or
        5. Torsion (3.3.6)

303A.3.4.6 SPC 5 Using ASCE 41

Structures shall be considered to comply with SPC 5 requirements of Table 2.5.3, Chapter 6 of the California Administrative Code where all of the following are satisfied:
  1. Immediate Occupancy structural Performance Level (S-1) in accordance with Section 2.3.1.1 of ASCE 41 at BSE-1N;
  2. Life Safety Performance Level S-3 in accordance with Section 2.3.1.3 of ASCE 41 at BSE-2N; and
  3. Items identified in Chapter 6, Article 10 of the California Administrative Code, satisfying the requirements of Operational Nonstructural Performance Level (N-A) in accordance with Section 2.3.2.1 of ASCE 41 at BSE-1N.

303A.3.4.7 NPC-2 and NPC-3 Using ASCE 41:

Operational Nonstructural Performance Level (N-A) and Position Retention Nonstructural Performance Level (N-B) of ASCE 41 at BSE-1N shall be considered equivalent to NPC 3/NPC 2 requirements respectively of Table 11.1, Chapter 6 of the California Administrative Code. For NPC 3/NPC 2, only components listed in Table 11.1, Chapter 6 of the California Administrative Code for NPC 3/NPC 2 need to satisfy the requirements specified above.
