1, reinforced concrete structure;

Concrete is made of cementing materials such as cement, sand, stone, water and a certain proportion of additives and admixtures. After solidification, it is as hard as stone, with good compressive strength, poor tensile strength and easy to break in tension.

In order to solve this contradiction and give full play to the compressive capacity of concrete, a certain number of steel bars are often added in the tensile area or corresponding parts of concrete, so that the two materials can be bonded into a whole and bear external forces together. This kind of reinforced concrete is called reinforced concrete. The bonding and anchoring capacity of reinforced concrete can be obtained in four ways:

(1) Chemical adsorption force at the interface between steel bar and concrete, also known as cementation force.

(2) The concrete shrinks, and the steel bars hold tightly to produce friction.

(3) Mechanical bite between uneven surface of steel bar and concrete is also called bite force.

(4) Hook, bend or weld short rebar and angle steel at the end of rebar to provide anchoring ability.

2. Steel structure;

Steel is characterized by high strength, light weight, good overall stiffness and strong deformation resistance, so it is especially suitable for building long-span, ultra-high and overweight buildings.

The material is an ideal elastomer with good uniformity and isotropy, which is most in line with the basic assumptions of general engineering mechanics. The material has good plasticity and toughness, can deform greatly and can bear dynamic load well; Short construction period; It has a high degree of industrialization and can be used for specialized production with a high degree of mechanization.

High strength steel should be studied in steel structure to greatly improve its yield point strength; In addition, new steel products such as H-beam (also known as wide flange steel), T-beam and profiled steel plate should be rolled to meet the needs of long-span structures and super high-rise buildings.

In addition, there is a light steel structure system, without thermal bridge, the building itself is not energy-saving. This technology solves the thermal bridge problem with clever special connectors. Small truss structure makes cables and water pipes pass through the wall, which is convenient for construction and decoration.

6. Bridge structure

The bridge structure is divided into 13 chapters. In the introduction of the first chapter, the composition, classification and structural system of bridges, as well as the achievements, present situation and development of bridge architecture are introduced. Secondly, the planning and design of bridge, including bridge design principles and scientific basis, bridge construction procedures, planning and preliminary design, bridge structure modeling and aesthetic point of view.

Through the study of this chapter, students can have an overall and general understanding of bridge engineering before learning the following contents. The second chapter introduces the design load of the bridge.

The third chapter introduces the characteristics of reinforced concrete materials. The fourth chapter discusses the structure of the beam bridge. The fifth chapter introduces the design of simply supported reinforced concrete beams. The sixth chapter introduces the design of prestressed concrete simply supported beam.

The fifth and sixth chapters introduce the upper and lower structures of common simply supported beam bridges from the aspects of structural types, structural characteristics, design methods and construction technology, which is the basic knowledge that students need to master.

In the seventh and eighth chapters of other bridge types, the general structure, construction and design characteristics of prestressed concrete continuous beams (rigid frame bridges), cable-stayed bridges, suspension bridges and arch bridges are briefly discussed.

Chapters 9 and 10 introduce simply supported steel plate beams and steel truss bridges and bridge supports respectively.

Chapter 1 1 introduces the basic structures of piers and abutments.

Chapter 12 briefly introduces the design of piers and abutments.

Chapter 13 introduces the basic types and structures of culverts.
