Style of the building of the new results to promote the construction of a powerful force of the county and the ecological culture of the county and county educational practice activities of the unit is mainly: the county and below county departments under the organs, enterprises and institutions directly under the township, street, and munity, village, nonpublic economic organizations, social organizations and other grassroots organizations. Agencies and branches, each single unit, follow the rules on internal institutions. Educational practice with step by adhere to the county leadership, leadership and leading cadres to focus on outstanding catch to directly contact the service of the masses of law supervision departments and window units, service industry, educational practice, pay attention to grasp the heavy towns, streets and villages, munity education activities and the masses of grassroots groups in close contact to strengthen, and the majority of Party members, cadres and the mass line line Marx doctrine view of the masses and the party39。s mass line educational practice activity in the city39。(14分) 解： （3分） （3分） 典型方程 （2分） （3分） （3分）Opinions and suggestions on the party39。解： 基本體系 典型方程 七、用位移法計(jì)算圖示剛架。（3分） （a）基本體系 （b） （c） （d）M圖（/7）（1分）（2分） ， （2分）（2分）六、用位移法計(jì)算圖示剛架，求出系數(shù)項(xiàng)及自由項(xiàng)。 （2分）圖如圖（c）所示。（16分）解： 基本體系及未知量如圖（a）所示。 解：(1) 一次超靜定，基本體系和基本未知量，如圖（a）所示。（10分） 四、用力法計(jì)算圖示結(jié)構(gòu)，作彎矩圖。三、作圖示靜定梁的彎矩圖。（ ）三、作圖示靜定梁的彎矩圖。（ √ ）96．反映結(jié)構(gòu)動(dòng)力特性的參數(shù)是振動(dòng)質(zhì)點(diǎn)的振幅。 ()94．用力矩分配法計(jì)算結(jié)構(gòu)時(shí)，結(jié)點(diǎn)各桿端力矩分配系數(shù)與該桿端的轉(zhuǎn)動(dòng)剛度成正比。（ ）92．位移法典型方程中的自由項(xiàng)是外因作用下附加約束上的反力?！ 。ā 獭。?0．圖示桁架結(jié)構(gòu)中不包括支座鏈桿，有5個(gè)桿件軸力為0 。（ ）88．當(dāng)結(jié)構(gòu)中某個(gè)桿件的EI為無窮大時(shí)，其含義是這個(gè)桿件無彎曲變形。 （ ）86．圖示結(jié)構(gòu)A截面彎矩影響線在A處的豎標(biāo)為l。 （ ） 84. 超靜定結(jié)構(gòu)由于支座位移可以產(chǎn)生內(nèi)力。（ √ ）82. 靜定多跨梁中基本部分、附屬部分的劃分與所承受的荷載無關(guān)。 （ √ ）80. 超靜定結(jié)構(gòu)的力法基本結(jié)構(gòu)是唯一的。 （）78. 圖示為剛架的虛設(shè)力狀態(tài)，按此力狀態(tài)及位移計(jì)算公式可求出A處的轉(zhuǎn)角。 （√）76. 結(jié)構(gòu)的自振頻率與結(jié)構(gòu)中某桿件的剛度無關(guān)。 （√）74. 結(jié)構(gòu)由于弱阻尼其自由振動(dòng)不會(huì)衰減。不考慮桿件的軸向變形，則體系振動(dòng)的自由度數(shù)為1。 （√）71. 圖示體系有3個(gè)振動(dòng)自由度。 （√） 69. 圖示簡(jiǎn)支梁支座反力FyB的影響線是正確的。 （√） 67. 圖示影響線中K點(diǎn)的豎坐標(biāo)表示P=1作用在K點(diǎn)時(shí)產(chǎn)生的K截面的彎矩。 （√）65. 靜定結(jié)構(gòu)的內(nèi)力和反力影響線是直線或者拆線組成。 （√）63. 靜定結(jié)構(gòu)剪力影響線是由直線段組成的。 （√）
