Through the analysis and studying of this subject, we can make conclusion as followed : during the whole heating season, the change law of the energy consumption of the thermal bridge is with the change law of the meteorological condition inside and outside the room : when airs temperatures indoor is steady, thermal bridge energy consumption increases with reducing of air temperature outside the room, reduce oppositely. the different position and the different structure patterns of the thermal bridges, even under the same meteorological condition inside and outside of the room, energy consumption of the building is different, and impact on heating energy consumption is different, this is mainly caused by the difference of the constructs thermal bridge and different influence in term of out wall, which lead to total mean heat - transfer coefficient different, when the heat - transfer coefficient is relatively small of outer wall, the impact of wall body is more obvious on heat - transfer coefficient of the thermal bridge
然後確立了在節能建築中熱橋耗熱量與室內外氣象參數和熱橋構造型式的關系，分析與研究並得出：在整個採暖季節中，熱橋的能耗隨著室內外氣象條件的變化規律是：在室內空氣溫度一定時，熱橋能耗隨著室外空氣溫度的降低而增大，相反減小；不同部位的熱橋，其構造型式不同，即使在相同的室內外氣象條件下，產生的能耗也是不同的，並且對採暖能耗的影響也不同，這主要是由於不同構造的熱橋對外墻的總平均傳熱系數的影響不同所造成的，並且當外墻主體的傳熱系數較小時，熱橋對墻體的傳熱系數的影響更加明顯。Firstly, the analyses on the dynamical response of the tsing ma bridge ( tmb ) under traffic loading are performed on the basis of the three dimensional finite element model of the full - scale structure of the bridge, and some regions critical to fatigue damage are determined from the result of the dynamical response. the hot spot stress approach is usually adopted in the fatigue design and analysis of tubular welded joints. to apply the hot spot stress approach for the fatigue evaluation of long - span suspension bridges, the fem is further used to determine the hot spot stress of the critical fatigue locations
首先，在青馬大橋三維有限元模型和整體動力響應分析計算的基礎上進一步進行關鍵疲勞構件的局部熱點應力分析，對疲勞危險部位處的焊接構件建立三維有限元模型，施加符合橋梁實際工況的載荷與位移邊界條件，進行局部熱點應力分析，確定這些焊接構件內的名義應力和相鄰焊接區域內熱點應力之間的關系，得到相應的應力集中系數。
