輕量化是輕鋼結(jié)構(gòu)更突出的特點(diǎn)。輕鋼結(jié)構(gòu)的承重構(gòu)件主要采用輕焊h型鋼、高頻焊型鋼、輕熱軋型鋼、冷彎薄壁型鋼等截面形式。在這些截面比普通截面多的情況下，輕鋼結(jié)構(gòu)比普通鋼結(jié)構(gòu)節(jié)省鋼材30%以上。單層輕鋼結(jié)構(gòu)廠房用鋼量一般為20~40kg/m2，冷彎薄壁鋼輕鋼屋面框架用鋼量一般小于15kg/m2。輕鋼結(jié)構(gòu)房屋的圍護(hù)結(jié)構(gòu)采用輕質(zhì)材料。圍護(hù)結(jié)構(gòu)與主體承重結(jié)構(gòu)均輕，結(jié)構(gòu)基礎(chǔ)形式簡(jiǎn)單，造價(jià)低。
　　Lightweight is the most prominent feature of light steel structure. The main load-bearing members of light steel structure are light welded H-beam, high frequency welded beam, light hot rolled beam and cold-formed thin-walled beam. In the case that these sections are more than ordinary sections, the steel of light steel structure is more than 30% less than ordinary steel structure. The steel consumption of single-layer light steel structure workshop is generally 20 ~ 40kg / m2, and that of cold-formed thin-walled steel light steel roof frame is generally less than 15kg / m2. The enclosure structure of light steel structure house adopts light material. The envelope structure and the main bearing structure are light, the structure foundation form is simple, and the cost is low.
　　2. 良好的抗震性能
　　2. Good seismic performance
　　輕鋼結(jié)構(gòu)鋼具有材料均勻、強(qiáng)度高、彈塑性性能好、動(dòng)載能力強(qiáng)、可靠性高、構(gòu)件失效前塑性變形大等特點(diǎn)。此外，輕鋼結(jié)構(gòu)自重輕，結(jié)構(gòu)抗震效果明顯降低，結(jié)構(gòu)整體抗震性能強(qiáng)。對(duì)于單層或低層的輕型鋼結(jié)構(gòu)，地震作用通常不受控制。例如，單層門式剛架結(jié)構(gòu)，一般不能做抗震驗(yàn)算。
　　Light steel structural steel has the characteristics of uniform material, high strength, good elastic-plastic performance, strong dynamic load capacity, high reliability and large plastic deformation before component failure. In addition, the self weight of the light steel structure is light, the seismic effect of the structure is significantly reduced, and the overall seismic performance of the structure is strong. For single story or low story light steel structure, seismic action is usually not controlled. For example, the single-layer portal frame structure, generally can not do seismic checking calculation.
　　3.裝配率高，工期短
　　3. High assembly rate and short construction period
　　輕型鋼結(jié)構(gòu)的建筑結(jié)構(gòu)簡(jiǎn)單，采用常規(guī)材料，主要零部件及配件均為工廠工業(yè)化生產(chǎn)，零部件加工精度高。組件自重輕，運(yùn)輸安裝方便，無需大型機(jī)械設(shè)備，現(xiàn)場(chǎng)安裝方便。除基礎(chǔ)施工外，基本無濕工，構(gòu)件間多采用螺栓連接，現(xiàn)場(chǎng)施工人員較少。與同規(guī)模的鋼筋混凝土結(jié)構(gòu)相比，輕鋼結(jié)構(gòu)的工期可縮短約1/3。
　　The building structure of light steel structure is simple, using conventional materials, and the main parts and accessories are industrialized production in the factory with high processing accuracy. The component has light weight, convenient transportation and installation, no need of large mechanical equipment, and convenient on-site installation. In addition to foundation construction, there is basically no wet work, and the members are mostly connected by bolts, with few on-site construction personnel. Compared with the reinforced concrete structure of the same scale, the construction period of light steel structure can be shortened by about 1 / 3.
　　4. 綜合經(jīng)濟(jì)效益好
　　4. Good comprehensive economic benefits
　　輕鋼結(jié)構(gòu)構(gòu)件截面小，可減少結(jié)構(gòu)本身在施工面積中的比例。同時(shí)也可以在一定程度上降低結(jié)構(gòu)的高度，增加建筑的有效利用面積。項(xiàng)目建設(shè)周期短，大大降低了投資成本，發(fā)揮了效益，使用早，投資回報(bào)快。輕鋼結(jié)構(gòu)的施工主要是千次作業(yè)，有利于文明施工，減少建筑浪費(fèi)。
　　The small section of light steel structure can reduce the proportion of structure in construction area. At the same time, it can also reduce the height of the structure to a certain extent and increase the effective use area of the building. The construction period of the project is short, the investment cost is greatly reduced, the benefit is brought into play, the use is early, and the investment return is fast. The construction of light steel structure mainly involves thousands of operations, which is conducive to civilized construction and reduces construction waste.
　　5. 節(jié)能環(huán)保
　　5. Energy conservation and environmental protection
　　輕鋼結(jié)構(gòu)的墻體重量輕、保溫隔熱、隔音性能優(yōu)于傳統(tǒng)墻體材料，符合建筑節(jié)能環(huán)保要求，可達(dá)到節(jié)能50%的目標(biāo)，節(jié)約人均資源相對(duì)不足。輕質(zhì)墻體材料為不燃阻燃材料，耐火時(shí)限可達(dá)1h以上。建筑裝修、圍護(hù)采取防火措施(防火板罩或防火涂料)后耐火時(shí)限可達(dá)2.5h。大部分建筑結(jié)構(gòu)材料都可以回收再利用，節(jié)約了大量資源，有利于環(huán)境保護(hù)。屬于“綠色建筑”，符合國(guó)家可持續(xù)發(fā)展政策和環(huán)保要求
　　The wall of light steel structure is light in weight, superior to traditional wall materials in heat preservation, heat insulation and sound insulation. It meets the requirements of building energy conservation and environmental protection, and can achieve the goal of 50% energy conservation. The per capita resource conservation is relatively insufficient. The light wall material is nonflammable and flame retardant, and the fire resistance time can be more than 1h. The fire resistance time limit of building decoration and enclosure can reach 2.5h after taking fire prevention measures (fire-proof board cover or fire-proof coating). Most of the building structural materials can be recycled, which saves a lot of resources and is conducive to environmental protection. It belongs to "green building" and conforms to the national sustainable development policy and environmental protection requirements
