At present , there are no information or specification on studying the transverse stiffener of the thinned - web beam systemically . and there are a small few literatures related on load - bearing ability and laying of the transverse stiffeners of the thinned - web beam 目前,只有極少資料簡單介紹了薄腹板梁橫向加勁肋的受力及設置等問題,尚未見薄腹板梁橫向加勁肋的系統研究文獻。

Results of the experiment shows that end - plate connections have excellent hysteretic behaviors , and the determination factors , which have crucial influence on the behavior , are end - plate thickness , column web thickness , and the rib stiffeners 試驗結果表明端板連接具有良好的滯回性能,端板厚度、節點域柱腹板厚度以及加勁肋構造是影響連接性能的主要因素。

The test results indicated that the performance of the composite panels can be well displayed if the types of steel stiffeners were adequately selected , the goggle pins were rationally laid out and the thickness of concrete was apropriately determined 試驗結果表明,通過適當地選擇型鋼加勁肋形式、合理地布置栓釘和確定混凝土厚度,可以保證組合作用的發揮。

Therefore the designs of stiffeners in the structures mostly depend on engineers “ experience , then lead to the using stiffeners “ stiffness and section are bigger . that make the waste of material too much and the design maybe not advisable 因此,實際工程設計中主要是依靠經驗,所取加勁肋的剛度、截面都比較大,耗材比較多,既浪費材料,也不一定合理。

The research has indicated : the bearing capacity and elastic stiffness of the vertical stiffener is bigger ; the length has do contribution both to the bearing capacity and stiffness ; the length just has influence on stiffness 研究表明:垂直加勁肋節點承載力、彈性剛度較大;垂直加勁肋長度對節點承載力和剛度都有貢獻;加勁肋高度只對節點剛度有影響。

The use of intermediate stiffeners in the compression plate may significantly increase elastic buckling stress and ultimate capacity of the plate . however , the behavior of the plate with intermediate stiffeners would be complicated 在受壓板件中設置中間加勁肋可以顯著提高板件的彈性屈曲應力和極限承載能力,但是也使得板件的屈曲行為變得復雜。

A program finite strip analysis model is formed and finite strip computer software is also made in this paper . the buckling behaviors of plates with flat - hat intermediate stiffener are analyzed by employing finite strip method 論文建立了有限條法分析模型,編制了有限條計算程序,用有限條法分析了帽形中間加勁板件的屈曲和帽形肋條的加勁性能。

For each stiffener element , the average stress - strain relationship under axial load as a beam - column in the flexural buckling mode is derived based on the approximate method , proposed by gordo and guedes scares 這種方法對傳統船型是有效的,但是它不能給出船體極強度的真實估算,而且當應用于非傳統船型時其計算結果不能令人滿意。

So by using finite - element method and taking the length and the height as main parameter , the bearing capacity , stiffness , stress distribution and destruction pattern of the vertical stiffener are analyzed 因此,采用有限元方法,以垂直加勁肋長度和高度為主要參數,對垂直加勁肋節點的承載力、剛度、應力分布和破壞模式進行了分析。

Smc / bmc ( dmc ) manhole cover : it refers to cmc that is mould pressed by smc / bmc ( dmc ) , other hard stuffing , the stiffener , etc . by 250 ~ 300t press under high temperature and pressure condition 井蓋:是指采用smc / bmc ( dmc ) 、其他硬質填充料、加強筋等經250 300t壓機在高溫高壓條件下,一次性模壓成型的復合材料窨井蓋。

The author analyses the tripping of stiffener and three patterns of panel ' s invalidation , so to get the curve of stress - strain of panel . this step is the core of the thesis 本文從理論入手,分析了加筋板單元中加強筋的側傾屈曲,然后根據加筋板的三種破壞模式,得到單元的應力應變關系曲線,這是本文的重點與難點。

On the basis of all these analyze , a reasonable dimension limitation for the flat - hat intermediate stiffener is given , in order to provide reference for designs and the revising of design specification 在分析基礎上,論文給出了中間帽形加勁肋合理尺寸的建議,可供設計和修訂設計規范參考。

The author established three t - stubs connections to simulate the three types of failure models . furthermore a model of no prying force model and a model with stiffener were made for analysis 撬力隨外加荷載變化的規律復雜,而且撬力的變化規律受節點剛度的大小和是否設置加勁肋的影響較大。

By using the types of stiffeners , the thickness of the composite panels and the arrangement of the goggle pins as the parameters , mechanical performance tests were made on 9 composite panels 以加勁肋形式、組合板厚度和栓釘布置為參數,進行了9塊組合板的力學性能試驗。

Cover layer and stiffener have similar properties , both possess high flexibility , good weather - ability , flame retardation , anti - ion - migration and heat resistance 覆蓋膜和補強版的黏膠設計,具有穩定的抗撕強度與耐噴錫性,并確保貼合時不塞孔、不包氣泡。

The effects for buckling stress of the changes of the stiffener rigidity , shape , dimension , as well as its location are analyzed in this thesis 論文對帽形中間加勁肋的剛度、加勁肋的形狀、尺寸和位置變化對中間加勁板件屈曲應力的影響作了分析研究。

The effects of longitudinal and transverse stiffeners on quasi - static crushing of stiffened square tubes are studied with the nonlinear finite element method 本文用非線性有限元方法研究了準靜態條件下縱向和橫向加強筋對加筋方形管壓潰破壞的影響。

Effects of column axial force and rib stiffener on hysteretic behavior of connections were synthetically considered for the first time during cyclic - loading 在循環加載試驗中首次綜合探討了柱軸力大小、加勁肋構造措施等對連接性能的影響。

To raise the critical stress of the web , we always lay some transverse stiffeners on the web , and also lay some longitudinal stiffeners sometime 為了提高腹板的臨界應力,通常都設有腹板橫向加勁肋,有時還在梁中段加設縱向加勁肋。
