It is a formed, sawed, or tooled groove in a concrete structure to create a weakened plane and regulate the location of cracking resulting from the dimensional change of different parts of the structure.

It is the length of embedded reinforcement required to develop the design strength of reinforcement at a critical section.

It is a method of pre-stressing in which tendons are tensioned after concrete has hardened.

It is a material encasing prestressing reinforcement to prevent bonding of the prestressing reinforcement with the surrounding concrete, to provide corrosion protection, and to contain the corrosion inhibiting coating.

Working stress refers to the actual stress developed in a material under a given load; while the maximum safe stress that a material can withstand is referred to:

It is the stress induced as a result of restrained deformations due to change in temperature:

It is a continuously wound reinforcement in the form of a cylindrical helix.

A point within a beam or column where no moment is developed and a point of a curve at which a change in the direction of curvature occurs, is called:

A long wall or embankment built to prevent flooding from the bodies of water.

It is a form of bracing where a pair of braces located either above or below a beam terminates at a single point within the clear beam span, is called:

It is an upright compression member with a ratio of unsupported height to average least lateral dimension not exceeding of 3:

It is a separation of an existing concrete slab from a new concrete slab or wall. A piece of expansion joint (usually ½” wide and made of cork or recycled fiber material) is placed against the existing concrete slab and when the new concrete slab is poured. This joint separates the two slabs.

It is used to fasten together components of a built-up member, such as a plate girder, and to make

connections between steel members using fusion in a controlled atmosphere and requires more skilled

ASTM steel with yield stress of 36000 psi has a symbol of:

The thickness of one-way slab should never be less than:

Slabs not exposed to weather and not in contact with the ground must have a minimum clear cover of:

The Coarse Aggregates in concrete must be larger than but not to exceed nominal size prescribed in Section 403.4.2 of NSCP:

Lap splices for uncoated deformed bar or wire must not be less than the larger of 48d_b and___.

Deformed bars larger than ___ mm should not be bundled.
