The structural failure of the foundation may occur if the foundation itself is not properly designed to sustain the imposed stresses 如果基礎(chǔ)本身未能正確設(shè)計以承受荷載所產(chǎn)生的應(yīng)力,基礎(chǔ)就可能產(chǎn)生結(jié)構(gòu)破壞。
Structural failures in recent earthquakes have exposed the weakness of current design procedures and shown the need for new concepts and methodologies for the seismic performance evaluation of structures 許多結(jié)構(gòu)在地震作用下的破壞已經(jīng)暴露出現(xiàn)行抗震設(shè)計規(guī)范的不足,要想對結(jié)構(gòu)的抗震性能做出一個比較準確的了解就需要新的觀念和新的方法。
Abstract : presents that the structural failure is fuzzy beside random , and introduces fuzzy maths into the monte carlo method in order to compute the structural failure probability . thus , all kinds of upmost limit state have been united . the examples show the suggested method is completely feasible 文摘:提出結(jié)構(gòu)的失效除了具有隨機性還應(yīng)具有模糊性的觀點,闡明了用模糊示性函數(shù)的蒙特卡洛方法計算失效概率的基本原理,從而將各種極限狀態(tài)統(tǒng)一起來,并使計算所得的失效概率更接近于實際.示例表明,本文方法是完全可行的
For a five bars truss structure , the introduction of the basic method of structural failure probability analysis is explained . based on o . ditlevsen ' s narrow bounds " algorithm and the numerical integration method in " m " space , a computer program to calculate failure probability of the five poles truss structure is given 針對五桿桁架結(jié)構(gòu)的失效概率問題,系統(tǒng)地介紹了結(jié)構(gòu)系統(tǒng)可靠性分析的基本方法;結(jié)合二階窄邊界法和“ m ”空間數(shù)值積分法編制了用于計算五桿桁架結(jié)構(gòu)失效概率的計算程序。
It is found that the rational located destressing boreholes can induce structural failure of the surrounding rock - mass , consequently the high stress move deeply in the rock - mass , and the stress environment in the surrounding rock is ameliorated , the spatio - temporal order of the destruction of the surrounding rock - mass is changed when the destressing boreholes and bolting net with wire mesh composite support are accomplished , therefore the compound supporting technology has prominent advantage for control the deformation and destruction of the surrounding rock 模擬發(fā)現(xiàn):合理布置的卸壓孔可以導(dǎo)致巷幫圍巖的結(jié)構(gòu)性預(yù)裂破壞,從而使圍巖高應(yīng)力向深部轉(zhuǎn)移;在卸壓孔和錨網(wǎng)聯(lián)合支護后改善了圍巖附近的應(yīng)力環(huán)境,改變了圍巖破壞的時空次序,對控制圍巖變形和破壞具有突出的優(yōu)越性。
In ultimate - state seismic design , energy spectra have been used for the reliable indices of seismic motions that determine their influences on structural failure and non - linear response . also , energy of ground motion can be viewed an index to incorporate the duration effect on structures , because longer duration usually induces a large energy demand . the duration of ground motion is so sufficiently taken into account 目前常用的反應(yīng)譜,無論是彈性或非彈性的,一個最大的缺憾是它們都沒有充分考慮輸入地震動持時的影響,但在能量譜中由于要反映隨著持時增長引起的能量變化,因而持時影響得到了充分的考慮,這是能量譜的一個十分重要的特點。
百科解釋
Structural failure refers to loss of the load-carrying capacity of a component or member within a structure or of the structure itself. Structural failure is initiated when the material is stressed to its strength limit, thus causing fracture or excessive deformations.
