问题 单项选择题

已知钢筋砖过梁净跨ln=1.5m,采用MU10的多孔砖和M5的混合砂浆砌筑,在距洞口0.6m高度处作用板传采的荷载标准值为10kN/m(其中可变荷载标准值为4kN/m),墙厚370mm(面荷载为7.43N/mm2)。

过梁上考虑的均布线荷载与下列()项数值最为接近

A.28.6kN

B.17.26kN

C.16.5kN

D.15.0kN

答案

参考答案:B

解析:

板距洞口高度hw=0.6m<ln=1.5m,应计入板传来的荷载

板的永久荷载为10-4=6(kN/m),可变荷载为4kN/m。

Laughter and tears are part of living. But do you find enough time for laughter? I am not asking if you  21  lost of good times.   22  we should laugh during the happy times. But do you also laugh during the  23  times?

Eram Bombeck is known for her humorous books, but she wrote one that  24  a more serious topic:  25 in children. Erma talks with many children with cancer and learns  26  life lessons from them. She learns, for instance, that cancer survivors know how to  27  .

She   28  the experience of 15-year-old Jessica from Burlinton. Jessica’s leg was cut off at the knee because of cancer. She was learning to  29  a prosthesis(假肢). Jessica tells about playing  30  . She kicked the ball  31 and it flew off in one  32  while her artificial leg flew into another. She fell on the  33  and laughed.

Jessica may not have laughed about her cancer, but she laughed about handling the  34  of it. And her laughter helped her a deal.

There is the story of 17-year-old Betsy. She   35  her way to the radiation room for her regular radiation therapy(化疗). As   36  , she dropped her hospital gown and, wearing only her birthday suit,  37 onto the table and waited. The extra people in the room were not the medical students she had thought, but   38 painters giving an estimate on painting! Betsy laughed heartily about the incident. And like Jessica, her  39  to laugh helped her to deal with one of the most difficult thing a young person can endure-cancer.

Do you find plenty of  40  for laughter? You can…if you also find reasons to laugh during the especially difficult times.

Survivors know how to laugh. If you can laugh even when the going is rough, you’ll make it. And you’ll smile at the end.
