The bonding and grinding mechanism of reinforcing bars is anchorage of reinforcing bars. However, due to the contact of the overlapping steel bars, the contact surface lacks enough concrete wrap and a certain grip force. In view of this, after research and practice, the researchers introduced a correction factor greater than 1 times the anchorage length to compensate for the standard application, that is, the length of lap joint. Therefore, lap length = anchorage length * correction factor.

　　我們知道11g101-1的鋼筋搭接需要我們計(jì)算，應(yīng)該說有點(diǎn)麻煩。但是，16g101-1的新版本要簡(jiǎn)單得多，直接提供表格，只要一對(duì)一的對(duì)應(yīng)就可以。16G101也是常用的結(jié)構(gòu)。

　　We know that the overlap of 11g101-1 steel bar needs our calculation. It should be said that it is a bit troublesome. However, the new version of 16g101-1 is much simpler, providing tables directly, as long as one-to-one correspondence. 16G101 is also the most commonly used structure.
