crack width of con</span><span style=\"font-family:Verdana;\">crete structure is an
important design aspect</span></span><span style=\"font-family:&quot;\"> </span><span style=\"font-family:Verdana;\">of the civil design. The four highly </span><span style=\"font-family:&quot;\"><span style=\"font-family:Verdana;\">recognized and widely used crack width theories are systematically </span><span style=\"font-family:Verdana;\">summarized. Based on the mentioned theories and
project practices, American</span><span style=\"font-family:Verdana;\"> code ACI system, Eurocode 2 1992-1 and
Chinese code GB</span></span><span style=\"font-family:&quot;\"> </span><span style=\"font-family:Verdana;\">50010
have different crack width control</span><span style=\"font-family:&quot;\"> </span><span style=\"font-family:Verdana;\">requirement and calculation methods. The crack width
control method based on ACI system code has evolved from the Z-factor method to
the steel bar spacing control method which is simple and easy to be adopted for
engineering. Meanwhile, the ACI 224.1R also gives a direct crack width
calculation method consistent with the steel bar spacing control method.</span><span style=\"font-family:&quot;\"> </span><span style=\"font-family:Verdana;\">The Eurocode 2 and GB 50010
based on the bond-slip &amp; no-slip theory consider much more affecting
factors than ACI for predicting crack width. Taking the crack width calculation
of Tunnel 5 intake as an example, the crack widths of the structure are
calculated according to ACI</span><span style=\"font-family:&quot;\"> </span><span style=\"font-family:Verdana;\">system
code, Eurocode 2 and GB 50010 respectively, the results</span><span style=\"font-family:&quot;\"> </span><span style=\"font-family:Verdana;\">show that the crack width results in various codes
are not much different.</span><span style=\"font-family:&quot;\"> </span><span style=\"font-family:Verdana;\">The EN
