This document discusses the design of foundations for a building located in Petrila, Hunedoara, Romania. It determines the depth of foundations as 5.35 meters based on soil conditions and frost depth. Isolated square foundations of reinforced concrete are selected, with dimensions of 2.0x2.0x0.7 meters. Loads and moments acting on the foundations are calculated. The document also calculates the pressures on the foundation base, designs the reinforcement for the concrete pad and pedestal, and checks settlement criteria.

This publication provides a concise compilation of selected rules in the Eurocode 8, together with relevant Cyprus National Annex, that relate to the design of common forms of concrete building structure in the South Europe. It id offers a detail view of the design of steel framed buildings to the structural Eurocodes and includes a set of worked examples showing the design of structural elements with using software (CSI ETABS). It is intended to be of particular to the people who want to become acquainted with design to the Eurocodes. Rules from EN 1998-1-1 for global analysis, type of analysis and verification checks are presented. Detail design rules for steel composite beam, steel column, steel bracing and composite slab with steel sheeting from EN 1998-1-1, EN1993-1-1 and EN1994-1-1 are presented. This guide covers the design of orthodox members in steel frames. It does not cover design rules for regularities. Certain practical limitations are given to the scope.

Transforming Brand Perception and Boosting Profitabilityaaryangarg12
In today's digital era, the dynamics of brand perception, consumer behavior, and profitability have been profoundly reshaped by the synergy of branding, social media, and website design. This research paper investigates the transformative power of these elements in influencing how individuals perceive brands and products and how this transformation can be harnessed to drive sales and profitability for businesses.
Through an exploration of brand psychology and consumer behavior, this study sheds light on the intricate ways in which effective branding strategies, strategic social media engagement, and user-centric website design contribute to altering consumers' perceptions. We delve into the principles that underlie successful brand transformations, examining how visual identity, messaging, and storytelling can captivate and resonate with target audiences.
Methodologically, this research employs a comprehensive approach, combining qualitative and quantitative analyses. Real-world case studies illustrate the impact of branding, social media campaigns, and website redesigns on consumer perception, sales figures, and profitability. We assess the various metrics, including brand awareness, customer engagement, conversion rates, and revenue growth, to measure the effectiveness of these strategies.
The results underscore the pivotal role of cohesive branding, social media influence, and website usability in shaping positive brand perceptions, influencing consumer decisions, and ultimately bolstering sales and profitability. This paper provides actionable insights and strategic recommendations for businesses seeking to leverage branding, social media, and website design as potent tools to enhance their market position and financial success.

Stabilirea adancimii de fundare:
Construcţia este situată în Petrila, judetul Hunedoara, zonă în care adâncimea de
îngheţ este 100...110cm. Deasemenea, este o construcţie definitivă, iar terenul este supus
îngheţului. Conform studiului geotehnic nu s-a gasit apa subterana, acesta efectuandu-se
pe o adancime de 7 m.
Datorită sistemului structural de rezistenta – cadru spatial din beton armat – al
cladirii si a terenului bun de fundare, sistemul de fundare ales este cel cu fundatii izolate,
alcatuite dintr-un bloc de beton simplu si un cuzinet din beton armat.
Adâncimea de fundare stabiliă este de -5.35 m faţă de CTN.
