# Experimental tests and numerical analysis of a real RC structure upgraded by means of C-FRP

Pollack Periodica
Author: Barecchia Enrico

The paper presents results of the analysis of the lateral-load response of an existing RC structure seismically upgraded by means of C-FRP. The structure was tested “as-is” under monotonic lateral loading conditions. It failed by a column-type collapse mechanism. The structure was repaired and upgraded by means of C-FRP. The structure has been tested again by a cyclic load test. Results demonstrate the successful implementation of C-FRP with a significant improvement of stiffness, strength and lateral displacement capacity of the upgraded structure. Finally a numerical study has been started with the aim to correctly capture the experimental results.

# An improvement of a theorem of Erdős and Sárközy

Pollack Periodica
Author: Gábor Horváth

Let a 1 < a 2 < … be an infinite sequence of positive integers and denote by R 2 ( n ) the number of solutions of n = a i + a j . P. Erdős and A. Sárközy proved that if g ( n ) is a monotonically increasing arithmetic function with g ( n ) → +∞ and g ( n ) = o ( n (log n ) −2 ) then | R 2 ( n ) − g ( n )| = o (√ g ( n )) cannot hold. We will show that for any ɛ > 0, the inequality | R 2 ( n ) − g ( n )| ≤ (1 − ɛ )√ g ( n ) cannot hold from a certain point on.

# Numerical simulation of the cyclic loading for welded beam-to-CFT column joints of dual-steel frames

Pollack Periodica
Authors: Cristian Vulcu, Aurel Stratan, and Dan Dubina

Dual-steel structural systems, in which mild carbon steel is used in dissipative members while high strength steel is used in non-dissipative ‘elastic’ members, can be very reliable and cost efficient. Because present seismic design codes do not cover this specific configuration, a research project started with the aim to investigate and evaluate the seismic performance of dual-steel building frames. The frames are considered to be moment resisting frames, dual concentrically braced frames and dual eccentrically braced frames. The paper makes a short description of the research project and the experimental program to be performed at the ‘Politehnica’ University of Timisoara.A number of numerical simulations have been performed for the beam-to-column joints that will be tested with the aim to assess their behavior under monotonic as well as cyclic loading. The material model used in the numerical simulations was calibrated based on the results from tensile tests. The assumptions considered in the modeling of the specimens, the loading procedure, as well as the results from the numerical analysis are finally presented.

# Meal replacements in Adults’ body weight management

Acta Alimentaria
Authors: I. Chirilă and E. Paulik

The purpose of the study was to assess the effectiveness of meal replacement diets in body weight management and the impact on the body composition of working age people, when the participants purchased the products and followed the weight loss program outside the clinical trial.In weight loss programs (3.98±2.29 months), 79 participants (56 women, 23 men) lost an average of 10.19±6.1 kg of their body weight, 11.47±9.15 cm in the waist circumference, and 5.29±5.46 of the percentage of body fat. Replacing two meals a day was an effective way to loose weight because of its simplicity and convenience of use. The cost of the products and the monotony of the diet were the main causes of abandoning the diet. After the diet subjects were followed for an average of 11.28±8.1 months, and for the entire group of participants an average weight gain of 2.86±3.02 kg was observed compared to the minimum weight (31.5% of weight lost). Long-term maintenance was better in the subjects that replaced one meal a day, but is still a challenge and required further research.
