Accounting for the additional stiffness of the steel, the nominal loading capacity P n for the column in terms of the maximum compressive stress of the concrete f c ', the yield stress of the steel f y, the gross cross section area of the column A g, and the total cross section area of the steel rebar A st
Above that zone, until wavelengths are comparable to the dimensions of the room, [a] room resonances dominate. This transition frequency is popularly known as the Schroeder frequency, or the cross-over frequency, and it differentiates the low frequencies which create standing waves within small rooms from the mid and high frequencies.

SCP – Containment Breach is an indie horror game developed by Joonas "Regalis" Rikkonen. It is based on stories from the SCP Foundation collaborative writing project. In the game, the player controls a human test subject, D-9341, who is trapped in an underground facility designed to study and contain anomalous entities known as SCPs. [2]
Room modes are the collection of resonances that exist in a room when the room is excited by an acoustic source such as a loudspeaker. Most rooms have their fundamental resonances in the 20 Hz to 200 Hz region, each frequency being related to one or more of the room's dimensions or a divisor thereof. These resonances affect the low-frequency ...
(2) The thermal expansion coefficients of concrete and steel are so close (1.0 × 10 −5 to 1.5 × 10 −5 for concrete and 1.2 × 10 −5 for steel) that the thermal stress-induced damage to the bond between the two components can be prevented. (3) Concrete can protect the embedded steel from corrosion and high-temperature induced softening.
The reinforcement is directed in the x, y and z direction. The reinforcement ratio is defined in a cross-section of a reinforcing bar as the reinforcement area over the total area , which is the brittle material area plus the reinforcement area.
Concrete cover, in reinforced concrete, is the least distance between the surface of embedded reinforcement and the outer surface of the concrete (ACI 130). The concrete cover depth can be measured with a cover meter. The purpose of concrete cover is to protect the reinforcement from corrosion, fire, and other potential damage.
Mod 2 (intended for fixed-wing aircraft launch) had a length of 2.75 m (9.0 ft) and an endurance of 6,000 m (3.2 nmi). All of the older versions used a lead-acid battery power source and carried a 45.4 kg (100 lb) warhead. [2] The present-day version is the A244/S Mod 3, manufactured by Leonardo Sistemi di Difesa. [3]
