超靜定連續(xù)梁影響線任務(wù)書

1、超靜定連續(xù)梁影響線及內(nèi)力包絡(luò)圖任務(wù)書一、任務(wù)1、求解超靜定連續(xù)梁影響線以及在均布活荷載作用下的最不利布置和內(nèi)力包絡(luò)圖。2、計(jì)算方法： （1）用力法求作連續(xù)梁支點(diǎn)彎矩影響線。 （2）用撓度法繪制連續(xù)梁支點(diǎn)彎矩影響線。二、計(jì)算書的要求1、用力法計(jì)算求得支點(diǎn)彎矩、的影響線；2、用撓度法計(jì)算求得支點(diǎn)彎矩、的影響線；3、求第二跨內(nèi)截面K的彎矩，剪力影響線及支座1的反力影響線；4、在求影響線的基礎(chǔ)上，進(jìn)行均布移動(dòng)荷載的最不利布置；5、連續(xù)梁承受均布活荷載及恒載時(shí)，繪出彎矩、剪力包絡(luò)圖。6、計(jì)算書要求步驟清晰，繪圖準(zhǔn)確，電子文檔，A4打印紙輸出，正文：宋體，小四字，單倍行距；頁面設(shè)置：頁邊距上下2.6cm、
