由于雕塑雕像結構的外形無論在平面還是立面方向都特別復雜,因此其內部結構的有限元建模工作要比一般的規則結構困難得多。
Because the shape of sculpture structure is very complex in both plane and elevation direction, the finite element modeling of its internal structure is much more difficult than the general regular structure.
其基本原則是:建模必須充分考慮外輪廓壁板的次安裝,即桿件和節點的布置,在預留一定的安裝空間后,必須滿足外形要求。具體布置方法是,依據像體外形的電子掃描曲線(通常沿高度方向每隔0.2~0.5m截取一根曲線),在每隔2m左右的一層曲線范圍內布置桿件和節點,每個節點離外輪廓曲線的近否則不能滿足二次安裝壁板的空間要求。節點之間距離,一般應控制在350~1布置的桿件,應盡量形成三角形的幾何不變體系,特別需要指出的是,在進行結構平面布置時,對于沿曲線方向的外圈邊梁,由于直接承受二次外掛壁板傳來的扭矩,其截面形式宜采用具有良好抗扭性能的封閉型截面,如方鋼管、圓鋼管等,不宜采用角鋼或H型鋼等開口截面。
The basic principle is: the secondary installation of the outer contour panel must be fully considered in the modeling, that is, the arrangement of members and nodes. After a certain installation space is reserved, the shape requirements must be met. According to the electronic scanning curve of the image shape (a curve is usually cut every 0.2-0.5m along the height direction), the members and nodes are arranged within the curve range of about 2m, and each node is closest to the outer contour curve, otherwise the space requirement for secondary installation of wall panel cannot be met. Generally, the distance between nodes should be controlled between 350-1 bars, and a triangle geometry invariant system should be formed as far as possible. In particular, for the outer ring side beam along the curve direction, the section form of the closed section with good torsion resistance should be adopted, for it directly bears the torque from the secondary external wall panel, such as square Steel pipe, round steel pipe, etc., should not use angle steel or H-section steel.
在各層平面的結構布置完成后,再進行豎向結構的布置,即沿像體高度方向連接各層平面上的節點,基本沿豎向的構件按柱截面設置,一般采用H型鋼或箱形截面,并注意其主軸的放置方向,斜向的構件按縱向支撐設置,通常采用等邊或不等邊的雙角鋼截面也可采用圓鋼管、方鋼管或H型鋼截面。
After the structural arrangement of each floor plane is completed, the vertical structural arrangement shall be carried out, that is, the nodes on each floor plane shall be connected along the height direction of the image, and the vertical components shall be set according to the column section, generally H-shaped steel or box section shall be adopted, and the main axis shall be paid attention to, the oblique components shall be set according to the longitudinal support, and the equal or unequal double angle steel section can also be adopted Circular steel pipe, square steel pipe or H-section.
這里需要注意的是:
Here we need to pay attention to:
?、僭谶B接像體外圍的豎向構件時,由于某兩層曲線之間像體的實際外輪廓可能存在內凹部分,此時該處的某些構件可能會與二次安裝的壁板位置相沖突即所謂的“犯界”
?、?When connecting the vertical components around the image, there may be a concave part in the actual outer contour of the image between two layers of curves. At this time, some components may conflict with the position of the second installation of the wall panel, which is called "boundary breaking"
?、谠诘裣竦纳眢w與頭,頸部輪廓突變處,應將桿件的網編織密切不能留有任何不牢固。
?、?In the body and head of the statue, where the contour of the neck changes, the net of the rod shall be woven closely without any unsteadiness.
