Description

"Building Bridges" Architecture and Shape PPT Courseware

Classification of bridges

According to shape: flat bridge, arch bridge, suspension bridge

According to materials: wooden bridge, brick bridge, stone bridge, steel bridge, concrete bridge, reinforced concrete bridge

According to length: extra large bridge, large bridge, medium bridge, small bridge

According to whether the bridge body is movable: fixed bridge, open bridge, floating bridge

Do it

Test the bearing capacity of arch bridges, cable-stayed bridges and flat slab bridges

Experimental requirements:

1. When building a beam bridge, use hard paper as the bridge deck and wooden blocks as the piers. The distance between the piers should be consistent with the length of the paper.

2. When building an arch bridge, another piece of cardboard should be made into an arch shape and placed under the flat bridge, with the top of the arch touching the bridge deck.

3. When building a suspension bridge, first tie two ropes of equal length to the chopsticks, and then tie the ropes to the center of the cardboard.

4. The same weight should be selected for the three bridges in order to compare the load-bearing capacity of various bridges.

5. Keep good records.

Little knowledge about bridge classification:

Various bridges can be divided into flat bridges, arch bridges, and suspension bridges according to their shapes; they can be divided into wooden bridges, brick bridges, stone bridges, steel bridges, concrete bridges, and reinforced concrete bridges according to their materials; and they can be divided into wooden bridges, brick bridges, stone bridges, steel bridges, concrete bridges, and reinforced concrete bridges according to their total length. It can be divided into extra-large bridges, large bridges, medium bridges and small bridges; according to whether the bridge body is movable, it can be divided into fixed bridges, open bridges and floating bridges; according to its use, it can be divided into railway bridges, highway bridges, pipeline bridges, multi-purpose bridges, etc. According to the crossing object, it can be divided into cross-river bridges crossing rivers, cross-valley bridges crossing valleys, cross-line bridges crossing railways or highways (also called overpasses), and viaducts crossing urban areas, industrial areas or agricultural areas.
