目前图书馆多数采用金属书架,而金属书架由于本身形制以及和馆内地面水平度等未能保持一致,因而在地震中经常发生倒塌、倾斜状况,容易造成图书的损毁、器具的毁坏和人员的伤亡。因此,明确书架的类型以及在地震中受损的情形与原因,有助于图书馆书架的选择与购取,也有助于图书馆的防震与抗震效能的提高。 At present, most libraries use metal shelves. Due to their own shape and the inconsistency with the ground level in the hall, the metal bookshelf often collapses and tilts in the earthquakes, causing damage to books, destruction of equipment and personnel casualties. Therefore, clarifying the types of bookshelves and the circumstances and causes of the damage in the earthquake will help the library bookshelf to choose and buy, and also help to improve the anti-seismic and anti-seismic performance of the library.
