厚度雖小，但橫向剪力所引起的變形和彎曲變形屬同一量級，在分析靜載荷下的應(yīng)力和變形時(shí)，仍須考慮橫向剪切效應(yīng)，垂直于板面方向的正應(yīng)力則可忽略。在分析動載荷下的應(yīng)力和變形時(shí)，除考慮橫向剪切效應(yīng)外，還須考慮微段的慣性力和阻尼力矩。中厚板在機(jī)械工業(yè)中早已有廣泛應(yīng)用。近年來由于高壓、高溫和強(qiáng)輻射的環(huán)境要求，工程中板的厚度有所增加，很多板件均改用中厚板理論進(jìn)行分析。

角鋼的規(guī)格用邊長和邊厚的尺寸表示。目前國產(chǎn)角鋼規(guī)格為2—20號，以邊長的厘米數(shù)為號數(shù)，同一號角鋼常有2—7種不同的邊厚。進(jìn)口角鋼標(biāo)明兩邊的實(shí)際尺寸及邊厚并注明相關(guān)標(biāo)準(zhǔn)。一般邊長12.5cm以上的為大型角鋼，12.5cm—5cm之間的為中型角鋼，邊長5cm以下的為小型角鋼。不等邊角鋼的截面高度按不等邊角鋼的長邊寬來計(jì)算。指斷面為角形且兩邊長不相等的鋼材。是角鋼中的一種。其邊長由25mm×16mm～200mm×l25mm。由熱軋軋機(jī)軋制而成。 </p> <p> <br /> </p><p> 圓鋼是指截面為圓形的實(shí)心長條鋼材。其規(guī)格以直徑表示，單位毫米(mm)，如“ 50mm”即表示直徑為50毫米的圓鋼。圓鋼與其它鋼筋的區(qū)別： </p> <p> 1、外型不一樣，圓鋼外型光圓，無紋無肋，其它鋼筋表面外型有刻紋或有肋，這樣就造成圓鋼與混凝土的粘結(jié)力小，而其它鋼筋與混凝土的粘結(jié)力大。 </p> <p> 2、成份不一樣，圓鋼(一級鋼)屬于普通低碳鋼，其它鋼筋多為合金鋼。 </p> <p> 3、強(qiáng)度不一樣，圓鋼強(qiáng)度低，其它鋼強(qiáng)度高，即直徑大小相同的圓鋼與其它鋼筋相比，圓鋼所能承受的拉力要比其它鋼筋小，但圓鋼的塑性比其它鋼筋強(qiáng)，即圓鋼在被拉斷前有較大的變形，而其它鋼筋在被拉斷前的變形要小得多。 </p> <p>
