Analysis of influence of the geometric parameters of mast systems on the natural frequency and vibration mode spectrum

MATEC Web of Conferences, 2017
Natural frequencies and eigenmodes of oscillations are the determining values in the study of dynamic processes in many constructions, including mast systems when they are affected by time-varying loads: wind, seismic, etc. [7].

Study on Chloride Ion Penetration Resistance of Rubberized Concrete Under Steady State Condition

MATEC Web of Conferences, 2016
Foamed concrete is a controlled low density ranging from 400kg/m3 to 1800kg/m3, and hence suitable for the construction of buildings and infrastructures. The uniqueness of foamed concrete is does not use aggregates in order to retain low density.
