IBC 2000》的1605节。⼆、ASD、LRFD可靠度的⽐较 1、LRFD的概率模型 最近我在看于炜⽂的《Cold-Formed Steel Design》，查到AISI⾥⾯LRFD⽅法的概率模型、两者可靠度指标的换算公式，触发灵机，决定从LRFD93和ASD89中寻找灵感，对AISC的ASD和LRFD⽅法⽐较。LRFD的概率模型：
ASD和LRFD方法计算轻钢结构屋面梁的安全度比较 朝花夕拾－2 ASD和LRFD方法计算轻钢结构屋面梁的可靠度比较－续篇 最近刚刚写完“朝花夕拾－15”，讨论了中美钢结构规范的可靠度问题，由于涉及到一些“朝花夕拾－2”的内容，于是把本篇文章再读一遍。读完之后不禁发笑；其实“朝花夕拾－2”本来就没有写的必要，因为AISC...

The HI-X74AJ grade guarantees no missing codes to 11-bit resolution over temperature; this means that all code combinations of the upper 11 bits must be present; in practice very few of the 12bit codes are missing. Unipolar Offset The first transition should occur at a level 1/2 LSB ...
Combinations of any of the above should also be included within the scope of computer-readable media. Computer-readable media may also be referred to as computer program product. FIG. 4 illustrates the architecture of a medical infusion pump 400 that can be used to implement aspects of the ...
