## PERMEABILITY OF CONCRETE

If concrete is impermeable, corrosive agents cannot penetrate and attack it. Concrete basically has two types of pores, which determine permeability. These are capillary pores (with a diameter varying between 0.01 to 10 micron) in the cement, paste which coats ...

## CIVIL ENGINEERING INTERVIEW QUESTIONS

Building materials and Construction What are the dimensions of the standard brick? What are thin shell roofs? Why are they becoming popular? Name the different types of retaining walls Structural Analysis What ...

## INDETERMINATE ARCHES

An arch may be defined as a plane-curved bar or rib supported and loaded in a way that makes it act in direct compression. For example, the structure in Fig. 1a is a parabolic symmetrical arch that is loaded with ...

## Analysis of Moment Resisting Frame and Lateral Load Distribution

Lateral Load Distribution of Frame BuildingIn a two dimensional moment resisting frame each joint can have at the most three degrees of freedom (displacement in horizontal and vertical directions and rotation). Total number of degree of freedom is 3Nj where Nj ...

## RELEVANCE OF CONSTRUCTION SCHEDULES

In addition to assigning dates to project activities, project scheduling is intended to match the resources of equipment, materials and labor with project work tasks over time. Good scheduling can eliminate problems due to production bottlenecks, facilitate the timely procurement ...

## BASIC ELEMENTS OF EARTHQUAKE RESISTANT DESIGN

Structures on the earth are generally subjected to load of two types static and dynamic. Static loads are constant with time while dynamic loads are time varying. The majority of civil engineering structures are designed with assumptions that all applied ...

## Guidelines for Earthquake Resistant Design of Structures

An earthquake is vibration of earth surface by waves emerging from the source of disturbance in the earth by virtue of release of energy in the earthâ€™s crust. It is essentially a sudden and transient motion or series of motions ...

## METHODS OF ANALYSIS OF FRAMES

Elastic analysis deals with the study of strength and behavior of the members and structure at working loads. Frames can be analyzed by various methods. However, the method of analysis adopted depends upon the types of frame, its configuration (portal ...

## QUALITY AND SAFETY CONCERNS IN CONSTRUCTION

Quality control and safety represent increasingly important concerns for project managers. Defects or failures in constructed facilities can result in very large costs. Even with minor defects, re-construction may be required and facility operations impaired. Increased costs and delays are ...

## Limit State, Working Stress and Ultimate Load Method of Structural Design

There are three methods of structural design, i.e. working stress, limit state and ultimate load method of structural design. These design methods are used for reinforced concrete as well as steel structure design. Methods of Structural DesignWorking stress method (WSM) Ultimate load ...
