中文拼音 [ruǎnhuàigāng]
軟壞鋼
英文
soft machinery steel-
I. a mtil ( iaxial elastic - plastic hardening - sofling constitutive model of concrete is proposed iii order to offer a nonlinear material model of concrete for space restoring force analysis of reinforced concrete members taking into account the softening behavior of concrete. the concrete material model is incorporated the elastic - plastic hardening fracturing constitutive model of concrete with the plastic - fracturing theory of concrete, modified without defining two loading functiomis, and based on five parameter power function failure criterion proposed by guo zheng - hai etc from tsingliua ( jniversity, or three parameter unified strength theory proposed by yu mao - hong from x ian iiaotong university
1 、將砼彈塑性硬化斷裂本構模型與塑性斷裂理論結合起來，並加以改進，但無需定義兩個加載面，以清華大學過鎮海建議的五參數冪函數或以西安交通大學俞茂宏建議的，參數統一強度理論作為砼的強度破壞準則，建立了砼多軸彈塑性硬化松馳本構模型，能為鋼筋砼構件空間恢復力分析提供砼非線性材料模型，並能反映砼材料的軟化段。Basing on rc simple supported beam the study of the paper is modal analysis using the finite unit software ansys, and the relationship among the transformation of vibration frequency, value of attached load, position of attached load, degree of damage, position of damage is discussed
本文利用大型有限元軟體ansys針對工程常用的鋼筋混凝土梁橋進行了模態分析，討論了振動頻率的變化與附加荷載大小、附加荷載位置、破損程度、破損位置之間的關系，研究了混凝土梁橋從完整階段到破壞階段振動頻率的變化規律。The research of this connection under monotonic and cyclic loading is simulated using powerful finite element analysis software. the damage mechanism under the moment loading is studied and the hysteresis curve is obtained. at last, the hysteresis model and the parameter of the model is defined to provide academic and numerical foundation
採用大型有限元通用軟體模擬該種連接在單調荷載和周期荷載作用下的試驗，研究了該連接在彎矩荷載作用下的破壞機理、做出了該連接的滯回曲線，並確定了滯回模型和模型參數，為研究半剛性連接鋼框架在地震荷載作用下的性能提供理論依據和實驗基礎。
