2.1 selection of steel

一般情況下經計算所得的梁柱截面，或是依托梁柱本身的強度進行控制，那么在進行鋼材選擇的時候，需要將強度作為，影響要素若是結構本身是根據變形或者是穩定性進行控制，那么需要考慮到使用低強度等級的鋼材。除此之外，根據當前我國所出臺的與鋼結構建筑有關的規范標準，門式剛架以及吊車梁和檁條等相關結構構件，需要選擇Q235-B或者是以上等級的鋼材作為主體結構材料使用。

In general, the calculated beam column section is controlled by the strength of the beam column itself. When selecting steel, the strength needs to be the first factor. If the structure itself is controlled according to deformation or stability, it needs to consider the use of low-strength steel. In addition, according to the current codes and standards related to steel structure buildings issued in China, steel of Q235-B or above grade shall be selected as the main structural material for portal frame, crane beam, purlin and other relevant structural components.

2.2焊接材料的選擇與使用

2.2 selection and use of welding materials

對于門式剛架輕型鋼結構房屋設計來講，應當在選擇焊接材料的時候，保證和鋼材的種類綜合進行考慮選擇和鋼材種類相同等級的焊條或者是焊絲作為焊接用材，尤其是那些直接承受動力荷載的焊接連接以及厚板焊接，應當選擇使用低輕型焊條，從而確保焊接材料的質量以及性能，能夠滿足鋼結構房屋建筑設計的強度及穩定性要求。

For the design of light-weight steel structure buildings with gabled frames, when selecting welding materials, it should be considered comprehensively with the types of steel, and the welding rods or welding wires of the same grade as the types of steel should be selected as welding materials, especially for those welding connections and thick plate welding that directly bear dynamic load, low-weight welding rods should be selected to ensure the quality and performance of welding materials, It can meet the strength and stability requirements of steel structure building design.

2.3螺栓選擇

2.3 bolt selection

對于門式剛架輕型鋼結構設計，應當通過高強度的螺栓和鋼結構對結構的主材料進行連接，在設計階段，應當對螺栓本身的性能等級，以及所連接材料的摩擦系數進行計算并確定，避免在選擇螺栓時出現選擇錯誤。一般情況下，在進行高強度螺栓連接時，主要選擇兩種分別是承壓型螺栓以及摩擦型螺栓。

For the design of portal frame light steel structure, the main materials of the structure should be connected through high-strength bolts and steel structure. In the design stage, the performance grade of the bolts themselves and the friction coefficient of the connected materials should be calculated and determined to avoid selection errors in the selection of bolts. In general, two types of high-strength bolt connection are mainly selected: pressure bearing bolt and friction bolt.

3.屋面支撐系統設計

3. Roof support system design

門式剛架輕型鋼結構房屋設計，在進行支撐設計與布置的過程中，需要將螺釘連接Z型或C型檁條，在此過程中還需要保證鋼結構房屋當中屋面板的厚度，以及鋼材版型和連接件的標準，從而使輕型鋼結構能夠擁有可靠的傳力結構。對于從業人員來講，需要注意的是在設計過程中，如果使用直立鎖縫屋面的時候，對于壓型鋼板以及連接件來講可能會出現相對滑動，所以不能夠當做檁條上翼緣的支撐，否則就可能會導致輕型鋼結構設計出現問題，所以要針對各結構的實際穩定性進行合理檢驗及計算，確保結構本身設計擁有合理性。還需要做好拉條以及撐桿系統的設計，上降低邊緣穩定缺失的降低，從而使鋼結構房屋整體的結構穩定性以及性得到提升。在實際計算過程中考慮到輕型鋼結構的實際狀況在每一項工作環節都需要進行合理安排，并選擇合適的節點構造，確保整個結構設計擁有合理性以及可行性。

In the design of portal frame light steel structure house, in the process of support design and layout, screws need to be connected to Z-shaped or C-shaped purlins. In this process, it is also necessary to ensure the thickness of roof slab in the steel structure house and the standards of steel plate and connectors, so that the light steel structure can have a reliable force transfer structure. For practitioners, it should be noted that in the design process, if the vertical seam roof is used, there may be relative sliding for the profiled steel plate and connectors, so it can not be used as the support of the upper flange of the purlin, otherwise it may lead to problems in the design of light steel structure. Therefore, it is necessary to conduct reasonable inspection and calculation according to the actual stability of each structure to ensure the rationality of the design of the structure itself. We also need to do a good job in the design of brace and brace system to minimize the reduction of edge stability loss, so as to improve the overall structural stability and safety of steel structure houses. In the actual calculation process, considering the actual situation of light steel structure, reasonable arrangement is required in each work link, and appropriate node structure is selected to ensure the rationality and feasibility of the whole structural design.

4.蒙皮效應分析

4. Skin effect analysis

對于門式剛架輕型鋼結構圍護設計，若是采用蒙皮設計方法，那么需要根據實際狀況對整體結構的設計要求進行確定，而且還需要對縱向邊緣構件以及連接件和螺釘件之間的間距進行合理優化配置，然后要結合工程的施工以及進度相關因素進行考慮，規避未來設計過程中不能夠滿足母體設計的需求時支撐系統所需要進行的修改。

For the enclosure design of portal frame light steel structure, if the skin design method is adopted, the design requirements of the overall structure need to be determined according to the actual situation, and the spacing between longitudinal edge members, connectors and screws need to be reasonably optimized, and then it should be considered in combination with the construction and progress related factors of the project, Avoid the modifications required by the support system when the requirements of the parent design cannot be met in the future design process.

5.整體變形問題

5. Overall deformation

對于整體變形問題來講一些有關的設計規范當中，只是針對鋼結構本身的橫向柱頂水平位移進行了優化限制，但從實際狀況來看，支撐系統本身的柔性變形以及塑性變形等相關因素也會導致位移問題的出現，對于的從業人員來講，應當在對門式剛架輕型鋼結構房屋設計過程中，采用剛性支撐等相應的措施來規避變形問題的出現，從而達到對房屋建筑結構整體進行調整與優化的效果。如果在工作過程中結構設受到特殊因素的影響，而不能夠進行圓鋼支撐設計，應當將剛性門架規避和原裝支撐共同進行使用，從而使鋼架側向位移以及扭轉的狀況得到明顯緩解，進一步使輕鋼結構設計的科學及合理性得到提升。

For the overall deformation problem, some relevant design codes only optimize and limit the horizontal displacement of the transverse column top of the steel structure itself, but from the actual situation, the flexible deformation and plastic deformation of the support system itself and other related factors will also lead to the displacement problem. For professional practitioners, they should be in the design process of portal frame light steel structure houses, Rigid support and other corresponding measures are adopted to avoid the occurrence of deformation problems, so as to achieve the effect of adjusting and optimizing the whole building structure. When the steel frame is designed, it can avoid the influence of the original steel structure and the torsion of the steel structure, so that the steel frame can be further protected from the special support during the design process.

6.抗風措施

6. Wind resistance measures

門式剛架輕型鋼結構房屋建筑，在使用過程中所面臨的更主要問題就是在大風天氣狀況下，房屋本身可能會面臨倒塌與傾斜的危險，所以基于當前鋼結構，房屋建筑工程的實際施工來看，在大風天氣狀況下，房屋的縱向尺寸如果十分小，那么鋼架柱子很可能會被直接拔出來，難以抵抗縱向風所產生的荷載。在這種狀況下進行鋼結構當中柱腳的設置是一項非常重要的工作，尤其是在風荷載比較大的地區，應當對鋼結構房屋的柱腳進行抗風措施設計充分衡量抗拔構造，并結合門式剛架的輕型鋼結構設計現實因素，對柱腳進行優化設計衡量。

The main problem faced by the light steel structure building with portal frame in the process of use is that the house itself may face the danger of collapse and inclination in windy weather. Therefore, based on the actual construction of the current steel structure and housing construction project, if the longitudinal size of the house is very small in windy weather, the steel frame columns are likely to be pulled out directly, It is difficult to resist the load caused by longitudinal wind. In this case, the setting of column base in steel structure is a very important work, especially in the area with large wind load, the wind resistance measures should be designed for the column base of steel structure house, the pull-out structure should be fully measured, and the column base should be optimized and measured in combination with the practical factors of light steel structure design of portal frame.

7.鋼梁分段問題

7. Steel beam segmentation

在輕型鋼結構房屋設計過程中，鋼梁分段不同可能會對結構本身的彎矩造成一些影響，所以在實際設計過程中，鋼梁分段的確定是較為重要的工作，為了保證后續工序得以順利開展設計工作人員應當基于實際施工要求，考慮到多方面因素對鋼梁分段進行確認。是要在設計過程中，應當針對鋼梁的拼接節點進行合理控制，上保證后續的加工工序能夠簡單快速，而且還需要避免將梁拆分成單件復雜形狀的構件。其次是應當保證鋼梁本身的分段情況可以滿足結構運輸的要求，設計工作人員應當從鋼梁分段的長度進行考慮對其進行限制，確保在運輸過程中車輛能夠有效轉彎，降低運輸過程中的費用控制與風險控制。就是應當考慮到安裝的便捷性，所以設計工作人員應當對鋼梁拼接節點進行合理控制。

In the design process of light steel structure houses, different steel beam sections may have some impact on the bending moment of the structure itself. Therefore, in the actual design process, the determination of steel beam sections is a more important work. In order to ensure the smooth development of subsequent processes, the design staff should confirm the steel beam sections based on the actual construction requirements and considering various factors. Firstly, in the design process, the splicing joints of steel beams should be reasonably controlled to ensure that the subsequent processing process can be simple and fast to the greatest extent, and it is also necessary to avoid splitting the beams into single components with complex shapes. Secondly, it should be ensured that the segmentation of the steel beam itself can meet the requirements of structural transportation. The design staff should consider the length of the steel beam segmentation and limit it, so as to ensure that the vehicle can turn effectively in the transportation process and reduce the cost control and risk control in the transportation process. Finally, the convenience of installation should be considered, so the design staff should reasonably control the steel beam splicing joints.
