The Expression of Seismic Design

The Expression of Seismic Design
Prominent visual indication of the bracing role of
these reinforced concrete members follows logically
from their location along a seismic separation joint.

Reinforced concrete flying buttresses
in keeping with the Gothic style of St.
Dominic’s Church in San Francisco were
added as part of a seismic retrofit.

The beam stubs on this reinforced concrete momentresisting frame building provide space for horizontal
reinforcing bars to be anchored outside the beamcolumn joints, where reinforcing tends to be congested.

rather than concealing, a seismic

by a steel moment-resisting frame

structure as a seismic retrofit.

T
Diagonal bracing on the exterior of University
Hall, UC Berkeley, proved to be an efficient
and non-disruptive seismic retrofit.
Degenkolb Engineers
here are practical reasons why the seismic design features of buildings, bridges, and other structures are obscured in the finished construction, rather than revealed. Steel must
often be covered with fireproofing, a structural wall that resists earthquake forces may look much like a nonstructural wall, and steel reinforcing bars that the engineer and
constructor took care to arrange in particular earthquake-resisting patterns are no longer visible once the concrete is poured.
However, the expression of seismic design could be more commonly explored in furtherance of either or both of these goals: (1) to more efficiently integrate the architecture with
the engineering design; and (2) to allow the general public to appreciate the seismic features of the construction they see everyday.
