1 濟(jì)南輕型鋼結(jié)構(gòu)有效的保證了剛架的平面外整體穩(wěn)定性。若檁條或檁托板孔徑過(guò)大過(guò)長(zhǎng)，隅撐就失去了應(yīng)有的作用。

Jinan's lightweight steel structure effectively ensures the overall stability of the rigid frame out of plane. If the aperture of the purlin or purlin support plate is too large or too long, the corner brace will lose its proper function.

2 隅撐角鋼與鋼梁的腹板直接連接，當(dāng)剛架受側(cè)向力時(shí)，使腹板在該處局部受到側(cè)向水平力作用，容易導(dǎo)致鋼梁局部側(cè)向失穩(wěn)。

The 2 corner brace angle steel is directly connected to the web plate of the steel beam. When the rigid frame is subjected to lateral force, the web plate is locally subjected to lateral horizontal force, which can easily lead to local lateral instability of the steel beam.

3 有的工程所用檁條僅用電鍍，造成工程尚未完工，檁條早已生銹。檁條宜采用熱鍍鋅帶鋼壓制而成的檁條，且保證一定的鍍鋅量。

Some projects only use electroplating for purlins, resulting in unfinished projects and rusting of the purlins. Purlins should be made of hot-dip galvanized strip steel and pressed, ensuring a certain amount of galvanizing.

4 因墻面開(kāi)設(shè)門(mén)洞，擅自將柱間垂直支撐一端或兩端移位。同一區(qū)隔的柱間支撐、屋面水平支撐與剛架形成縱向穩(wěn)定體系，若隨意移動(dòng)其位置將會(huì)破壞其穩(wěn)定體系。

Due to the opening of a door on the wall, one or both ends of the vertical support between the columns were moved without authorization. The longitudinal stability system is formed by the support between columns, horizontal support on the roof, and rigid frame in the same partition. If its position is moved arbitrarily, it will damage its stability system.

5 有些單位為了節(jié)省鋼材和人工，將檁條和墻梁用鋼板支托的側(cè)向加勁肋取消，這將影響檁條的抗扭剛度和墻梁受力的可靠性。故施工單位不得任意取消設(shè)計(jì)圖紙的一些做法。

In order to save steel and labor, some units have removed the lateral stiffeners supported by steel plates for purlins and wall beams, which will affect the torsional stiffness of purlins and the reliability of wall beam forces. Therefore, the construction unit shall not arbitrarily cancel some practices of design drawings.

6 有的單位擅自增加屋面荷載，原設(shè)計(jì)未考慮吊頂或設(shè)備管道等懸掛荷載，而施工中卻任意增加吊頂?shù)葢覓旌奢d，從而導(dǎo)致鋼梁撓度過(guò)大或坍塌。任何單位均不得擅自增加設(shè)計(jì)范圍以外的荷載。

Some units increase roof loads without authorization, without considering suspension loads such as suspended ceilings or equipment pipelines in the original design. However, during construction, they arbitrarily increase suspension loads such as suspended ceilings, resulting in excessive deflection or collapse of steel beams. No unit shall increase the load beyond the design range without authorization.

7 屋面板未按要求設(shè)置，將固定式改為浮動(dòng)式，使檁條側(cè)向失穩(wěn)。往往設(shè)計(jì)檁條時(shí)，會(huì)考慮屋面壓型鋼板與冷彎型鋼檁條牢固連接，能可靠的阻止檁條側(cè)向失穩(wěn)并起到整體蒙皮作用。

The 7 roof panels were not set as required and were changed from fixed to floating, causing lateral instability of the purlins. When designing purlins, it is often considered that the roof profiled steel plate is firmly connected to the cold-formed steel purlins, which can reliably prevent lateral instability of the purlins and play an overall skin role.

8 剛性系桿、風(fēng)拉桿的連接板設(shè)置位置高低不一，使得水平支撐體系不在同一平面上，從而影響剛架的整體穩(wěn)定性。剛性系桿與風(fēng)拉桿構(gòu)成水平支撐體系，其設(shè)置高度在同一坡度方向應(yīng)保持一致。

The position of the connecting plates for the 8 rigid tie rods and wind pull rods varies, resulting in the horizontal support system not being on the same plane, thereby affecting the overall stability of the rigid frame. The rigid tie rod and wind tie rod form a horizontal support system, and their setting height should be consistent in the same slope direction.
