新规范中为何无烟囱、水塔等构筑物及钢筋混凝土异型往结构的抗震设计内容?本次建筑抗震设计规范的修订,已不包括烟囱、水塔等构筑物的抗震设计内容,此部分内容即将归入修订的《构筑物抗震设计规范》。对于异型柱结构,目前工程抗震界业内专家有各种不同的看法,普遍认为异型柱结构属于抗震不利的结构体系,目前正在修订的国家标准和行业标准均未将其列入。若采用异型柱结构又无地方法规者,属于超规范、超规程设计,应按国务院《建筑工程勘察设计管理条例》第29条的要求执行。
The new code why no chimneys, water towers and other structures and reinforced concrete shaped structure to the seismic design? The seismic design code revision, has not included the chimney, water tower and other structures seismic design content, this part is about to be included in the amendment The “seismic design code”. For the special-shaped column structure, there are various opinions among experts in the field of seismic engineering in the industry at present. It is generally accepted that the special-shaped column structure belongs to a structural system unfavorable to earthquake resistance and is not included in the revised national and industrial standards. If the use of special-shaped column structure without rules and regulations, are super-normative, super-rules design, should be the State Council, “Construction Engineering Investigation and Design Regulations,” the implementation of Article 29 requirements.
