Structural Design Guide to the ACI Building Code
This book is intended to guide practicing structural engineers familiar with earlier
ACI building codes into more profitable routine designs with the ACI 1995
Building Code (ACI 318-95).
Each new ACI Building Code expresses the latest knowledge of reinforced
concrete in legal language for safe design application. Beginning in 1956 with
the introduction of ultimate strength design, each new code offered better utilization
of high-strength reinforcement and the compressive strength of the concrete
itself. Each new code thus permitted more economy as to construction
material, but achieved it through more detailed and complicated design calculations.
In addition to competition requiring independent structural engineers to
follow the latest code for economy, it created a professional obligation to follow
the latest code for accepted levels of structural safety.
The increasing complexity of codes has encouraged the use of computers for
design and has stimulated the development of computer-based handbooks.
Before computer software can be successfully used in the structural design of
buildings, preliminary sizes of structural elements must be established from
handbook tables, estimates, or experienced first guesses for input into the computer.
This book will guide the user to the various sections of the Code pertinent to
design of common reinforced concrete structural elements. A brief explanation
of the significance of these sections is presented, together with limits of applicability,
the range in which results may control design; and, where possible,
design short cuts to ensure automatic conformance to the Code without calculations.
This Guide does not duplicate nor replace the ACI Code, its Commentary,
design handbooks, or use of computers. It complements the ACI Code and Commentary,
shows how to take full advantage of available handbooks based on the
Code, and should shorten time to develop computer design programs. It converts
some code formulas from the review form (or trial designs) to direct design. It
presents some simple appropriate formulas, tabulations, and charts for conservative
