Deflection diagram for frames shows the displacement of each point along the frame under load.

• Deflection diagrams are used to visualize how a frame deforms under load.

• They show the displacement of each point along the frame in response to applied loads.

• The shape of the deflection diagram can help engineers analyze the structural integrity of the frame.

• Common types of deflection diagrams include bending moment diagrams

Bending moment diagram shows variation of bending moment along the length of a frame.

• Bending moment diagram helps in analyzing the internal forces in a frame.

• It is plotted with distance along the frame on x-axis and bending moment on y-axis.

• Points of zero bending moment indicate locations of maximum bending moment.

• The diagram can be used to determine the critical sections of a frame.

• Example: A simply supported beam wil...read more

Bearing articulation for curved spans involves designing bearings that can accommodate the movement and rotation of curved structures.

• Consider using spherical bearings for curved spans to allow for movement in multiple directions.

• Ensure proper alignment and spacing of bearings to accommodate the curvature of the span.

• Utilize flexible bearings or sliding bearings to account for the changing angles and forces in curved s...read more

Design of pier involves considering various factors such as load capacity, soil conditions, water level, and environmental impact.

• Determine the load capacity and type of pier required

• Analyze soil conditions and water level to determine foundation type

• Consider environmental impact and regulations

• Design for durability and maintenance

• Ensure safety measures are in place

Rigid pile caps are designed to transfer the load from the superstructure to the piles. The design should consider the pile arrangement, load distribution, and soil properties.

• The pile cap should be designed to distribute the load evenly to the piles.

• The pile arrangement should be considered to ensure that the pile cap is not overloaded.

• The soil properties should be analyzed to determine the bearing capacity of the pil...read more

Prestressing losses occur during the transfer of prestress from the jacks to the concrete. These losses can be divided into two stages.

• The first stage is immediate losses, which occur due to friction between the strands and the ducts, anchorage slip, and elastic shortening of the concrete.

• The second stage is time-dependent losses, which occur due to creep and shrinkage of the concrete, relaxation of the steel, and temp...read more

Design of steel members and connections involves determining the appropriate size and shape of steel components and how they are connected.

• Consider the loads and stresses that the steel members will be subjected to

• Select appropriate steel sections based on their strength and stiffness

• Design connections that can transfer loads between members without failure

• Ensure that the design complies with relevant codes and standar...read more

Pre-tension is applied before concrete is poured, while post-tension is applied after concrete has hardened.

• Pre-tension involves stretching steel cables or bars before pouring concrete to create tension in the concrete as it sets.

• Post-tension involves inserting steel cables or bars into hardened concrete and then tensioning them to create compression in the concrete.

• Pre-tension is typically used in precast concrete ele...read more

Analysis and design of piles involves determining the load capacity and selecting the appropriate type of pile for a given soil condition.

• Pile load capacity is determined through various methods such as static load tests, dynamic load tests, and pile integrity tests.

• Factors such as soil type, groundwater level, and seismic activity must be considered when selecting the type of pile.

• Common types of piles include driven ...read more
