As for traffic load , two situation were analyzed , symmetrical load and asymmetric load , in each of them , crack top ' s tension stress , shear stress and stress intensity factor were calculated , also the effect of structural parameters were analyzed 把交通荷載分為對(duì)稱(chēng)荷載和偏載兩種情況,計(jì)算了裂縫尖端的拉應(yīng)力、剪應(yīng)力以及強(qiáng)度因子,并對(duì)路面結(jié)構(gòu)進(jìn)行了參數(shù)分析。
Firstly , with uniaxial symmetrical rectangle cross section , the warping displacement function and tangential displacement function under anti - symmetrical load are supposed . then taking shear deformation into account and with potential principle , the governing differential equation for distortion angle subjected to uniformly distributed distortion load is established 首先,以單軸對(duì)稱(chēng)矩形截面薄壁桿件為研究對(duì)象,假設(shè)其在反對(duì)稱(chēng)荷載作用下翹曲位移和切向位移的分布函數(shù),考慮剪切變形的影響,利用最小勢(shì)能原理建立單位均布畸變荷載作用下的畸變角微分方程。
For the first time , based on frame structure with large thick raft plinth and many engineering examples , analytic method of interaction that means the analysis on three parts above as a whole with a full consideration of interaction thereof that met the need of the deformation correspond on the boundary was used to research on the interaction of structure and groundsill in this paper . and five models were adopted , which were : ( 1 ) a tube with symmetrical double - axis structure and symmetrical loads , ( 2 ) two tubes with symmetrical double - axis structure and symmetrical loads , and ( 3 ) a tube with symmetrical single - axis structure and symmetrical loads , and ( 4 ) two tubes with symmetrical double - axis structure and unsymmetrical loads , and ( 5 ) two tubes with unsymmetrical structure and loads . based on the middle - thick slab theory from mindli and the model for groundsill from winkle , the deformation character of raft foundation and the distributing rule for resisting force of fundus were studied in details by using b ig - style fem ( finite element member ) software , ansys 本文結(jié)合了大量的工程實(shí)例,以大底盤(pán)框架厚筏結(jié)構(gòu)形式為研究對(duì)象,針對(duì)單個(gè)和多個(gè)塔樓布置于同一個(gè)大底盤(pán)框架厚筏基上的復(fù)雜結(jié)構(gòu)體系,分( 1 )一個(gè)塔樓:結(jié)構(gòu)布置雙軸對(duì)稱(chēng),荷載對(duì)稱(chēng)的情況; ( 2 )兩個(gè)塔樓:結(jié)構(gòu)布置雙軸對(duì)稱(chēng),荷載對(duì)稱(chēng)的情況; ( 3 )一個(gè)塔樓:結(jié)構(gòu)布置單軸對(duì)稱(chēng),荷載對(duì)稱(chēng)的情? ; ( 4 )兩個(gè)塔樓:結(jié)構(gòu)布置雙軸對(duì)稱(chēng),荷載不對(duì)稱(chēng)的情況; ( 5 )兩個(gè)塔樓:結(jié)構(gòu)布置和荷載均不對(duì)稱(chēng)的情況等五種組合情況,全面系統(tǒng)地探討了上部結(jié)構(gòu)?基礎(chǔ)?地基相互作用的大跨度基礎(chǔ)、基礎(chǔ)板變形特征及其基底反力的分布規(guī)律。
