The test study of the brick wall cement mortar reinforced with steel mesh indicates : when the consolidated brick wall fail in bending - shear, its ultimate horizontal load and drift stiffness respectively is 1. 5 and 2 times bigger than that of brick wall
試驗表明，經鋼筋網水泥砂漿面層加固的墻體；在發生彎剪破壞時，極限水平荷載可以達到原墻抗剪強度的1 . 5倍以上，抗側剛度可以達到原墻體的2倍以上，剛度的提高大於強度的提高。 -
The mechanic character, destroying pattern, the ductile and dissipation energy capacity of this composite structure under the earthquake have been clarified. the stiffness degradation, natural frequency, damping ratio of this structural system with the development of intensity of earthquake have also been investigated. with consideration of the top displacement, drift of story and micro - strain of longitude steel bars, the equivalent shell wall method has been presented in order to simplify the design of such type structure
通過試驗，掌握了該結構體系在水平地震荷載作用下的受力特點、變形與耗能性能、結構的破壞形態等力學指標：得到了結構在不同地震烈度條件下的剛度變化、自振頻率、阻尼比等動力特性；綜合結構的頂點位移、層間轉角以及鋼筋的微應變，提出了適合於該結構體系簡化設計的「等效剪力墻法」 。 -
Eccentrically braced steel frames are a lateral load - resisting system which apply high intensity area and it can provide the high elastic stiffness that met higher steel building drift requirement. the links of eccentrically braced steel frames sustain large inelastic deformation without loss of strength under severe earthquake loading which demonstrate excellent energy - dissipation capacity and ductility
在罕遇地震時，由於耗能梁段屈服進入塑性，結構有很強的耗能能力和延性，是適用於高烈度震區的一種有效的抗側力結構體系。 -
Based on these principles and equations, this paper attempts to give a prepositional equation for simplified analysis for second - order drift. through the elementary research on second - order drift limits, this paper gives a second - order drift limit to one - bay - one - story steel frames, a second - order total building drift limit and a inter - story drift limit to multi - stories steel frames
本文在這些理論的基礎上，系統考慮了豎向荷載對側移影響、假想荷載對側移的影響和側移計算時的荷載組合等問題，嘗試性地提出了二階側移簡化計算的建議公式。 -
Code for design of steel structure gb50017 - 2003, the being employed code in china, has codified the basic theory about second - order analysis, but there is no criteria about second - order drift, and the drift limits in the code can be only used in first - order lateral displacements analysis. therefore, it is urgently that researches are needed on second - order drift analysis and on how to establish the new limits for second - order drift. it ’ s a practical problem that researching how to establish second - order drift limits, and some conditions relative practical engineering are required to be taken into account
我國現行規范《鋼結構設計規范》 （ gb50017 - 2003 ）已經將二階分析的原理列入其中，但規范中尚未涉及二階側移計算的有關內容，規范中規定的側移限值也僅限於對一階側移的約束，這就迫切需要對二階側移計算方法進行研究，以及確立考慮二階效應后鋼框架結構的側移限值。
