The possible shear of the upper chord will change beam from flexural member to member under flexure and compression force . this is emphasised through design example . as a result , we find that composite floor system is good for reducing the height of floor system 在組合樓蓋體系設(shè)計(jì)中,筆者指出,可能的桁架弦桿剪力會(huì)使作為桁架弦桿側(cè)向支承的梁由彎曲構(gòu)件變?yōu)閴簭潣?gòu)件,這是在與桁架體系相適應(yīng)的樓蓋體系設(shè)計(jì)中應(yīng)該注意的一個(gè)環(huán)節(jié)。
In this paper , based on a typical plan arrangement of two - user - on - one - storey and leap storey type multi - story house , the mechanical behaviours of the truss system , the difficulties in designing the truss system and the design of composite floor system is deeply analysed ; the connection design , fire proofing and corrosion protection used in this structure system are briefly introduced 本論文以一梯兩戶(hù)躍層式多層住宅的一種典型平面布置為依托,以構(gòu)思該住宅結(jié)構(gòu)體系設(shè)計(jì)的方式,對(duì)這種桁架體系的受力性能、設(shè)計(jì)難點(diǎn)和應(yīng)用于該結(jié)構(gòu)體系的壓型鋼板?混凝土組合樓蓋的設(shè)計(jì)進(jìn)行了深入分析,對(duì)結(jié)構(gòu)采用的連接、墻體和防火防腐措施進(jìn)行了簡(jiǎn)單討論。
