The program permits citizens from 51 countries and regions including the United States, Australia, Canada and Japan who have valid visas and flight tickets to a third country to spend three days in the city. The capital of Sichuan province is the first city in the western region of China to offer foreign tourists a threeday visa and the fourth nationwide to adopt the policy following Shanghai, Beijing and Guangzhou. Li Zhiyong, deputy dean of the tourism institute at Sichuan University, said the move contributes to a large increase in the number of overseas tourists and raises the city39。 （a） （b） （c） （d） （f）用位移法計算圖示剛架，求出系數(shù)項和自由項。 作出一半剛架彎矩圖如圖（b）所示。 參考答案：(1) 一次超靜定，基本體系和基本未知量，如圖（a）所示。　?。ā??。? （a） （b）37．在結(jié)構(gòu)動力計算中，兩質(zhì)點的振動體系，其振動自由度一定為2。（ ）29．在力矩分配法中，當(dāng)遠(yuǎn)端為定向支座時，其傳遞系數(shù)為1 。（ √ ）21．力法典型方程的等號右端項不一定為0。（√ ）13．靜定多跨梁中基本部分、附屬部分的劃分與桿件的剛度有關(guān)。（ ）5．桁架結(jié)構(gòu)在結(jié)點荷載作用下，桿內(nèi)只有剪力。 A． B． C． D．34．用位移法求解圖示結(jié)構(gòu)時，基本未知量的個數(shù)是（ B ）。A．直線段組成 B．曲線段組成C．直線曲線混合 D．二次拋物線12．靜定結(jié)構(gòu)反力與內(nèi)力的影響線形狀特征是（A ）A．直線段組成 B． 曲線段組成C．直線曲線混合 D．變形體虛位移圖13．同一結(jié)構(gòu)，不考慮阻尼時的自振頻率為ω，考慮阻尼時的自振頻率為ωD，則（C?。〢． B． C． D ．與的關(guān)系不確定14．在圖示結(jié)構(gòu)中，使體系自振頻率減小，可以 （ C ）A．減小 B．減小m C．減小EI D．減小l15．在圖示結(jié)構(gòu)中，為使體系自振頻率增大，可以 （ C ）A．增大 B．增大m C．增大EI D．增大l16．圖示a、b兩體系的EI相同，其自振頻率與的關(guān)系為 （ D ）。A． 不確定 B． C． D． 17．圖示結(jié)構(gòu)中，除橫梁外，各桿件EI = 常數(shù)。A． 2 B． 3 C． 4 D． 535．用位移法計算超靜定剛架時，獨立的結(jié)點角位移數(shù)等于（ B ）A．鉸結(jié)點數(shù) B．剛結(jié)點數(shù)C．多余約束數(shù) D．不確定36．力法典型方程是根據(jù)以下哪個條件得到的（ C ）。（ ）6．在桁架結(jié)構(gòu)中，桿件內(nèi)力不是只有軸力。（ ）14．基本附屬型結(jié)構(gòu)的計算順序是：先計算附屬部分后計算基本部分。 （ √ ）。 （ ）30．當(dāng)AB桿件剛度系數(shù)時，桿件的B端為定向支座。 （ ）38．反映結(jié)構(gòu)動力特性的參數(shù)是振動質(zhì)點的振幅。 (2) 列力法方程 (3) 作圖，見圖（b） 作圖，見圖（c） (4) 計算d1D1P（kN） （a） （b） （c）(5) 作圖 ，EI=常數(shù)。 作后彎矩圖如圖（c）所示。 參考答案： 基本體系 用位移法計算圖示剛架，求出系數(shù)項及自由項。s level of internationalization.
