“…Five possible structural solutions are investigated. There are three cases of steel frames (Case 1, Case 2 and Case 3); those significant differences are due to the initial rotational stiffness of the beam-to-column joints [65][66][67], one frame from the precast RC columns and beam (Case 4), and one frame from the precast RC columns and steel beam (Case 5).…”

Structural designers that design buildings use different criteria to select the frames’ materiality and structural solutions. Very often, the primary test is the cost of construction. Sometimes, solutions are determined by the terms of structure, architectural preferences, technological needs, fire safety requirements, environmental conditions, exploitation costs over the life of the building, ecological aspects, and experience, etc. This paper proposes an approach for analyzing the structural elements of buildings taking into account the impact on the environment using jointly incorporating subjective and objective aspects. The objective to combine the most important criteria into a single unit and carry out the overall assessment could be done by giving each variable a weighted value and perform a so-called multi-criteria analysis. This article shows the efficiency of the structural solution of the one-story building. The case study presents an investigation and comparison of five possible symmetrical structural solutions by multi-criteria assessment methods: The analysis of three steel frameworks differs majorly due to the beam-column characteristics, as well as precast RC frame structures case and combined steel beams and RC columns frame option. Possible solutions must meet all the essential requirements of the building, including mechanical resistance and stability. The obtained results show a broad assessment of the structural solutions of the building.

“…According to the combination and load variability, the most sensitive is the frame where variable load evenly distributed over the entire first floor and with semi-rigid joints. Sensitivity is further increased by flexibility of the joints (Daniūnas & Urbonas, 2010). A rigid frame is not sensitive in any case and requires no further calculations.…”

This paper presents the importance of the second-order effects in behaviour of steel frame structures. EN 1993-1-1 were distinguished three main methods: taking / without taking into account second order effects depending on the sensitivity of horizontal design effects and tolerance. Using these methods, the susceptibility of steel frame structures to second-order impacts is considered in accordance with EN 1993-1-1. The study was performed taking into account also the rotational stiffness of the joints of the frame structure. In this way, trying to determine the effect of the joint on the rotational rigidity makes the frame structure more sensitive to second order impacts. It is also considered a semi-rigid joints effects the general frame-tailed P-Δ and the second row stress. This establishes the link between the effects of the second-order and the semi-rigid joints in the overall (general) analysis. Frame-building sensitivity makes it possible to compare and measure the importance of such dependencies.Keywords: steel frame, structural analysis, second order analysis, semi-rigid joints, finite element method, sensitivity of the second order effects.

The results are dependent, too, on the definition and mathematical description of the structure limit states, and they can differ, e.g., when taking into consideration time dependent effects [13][14][15], when modeling macro and microscale behaviour of materials [16][17][18], when solving stability problems [19][20][21], and when describing system imperfections for nonlinear solutions [22].

In the present paper, reliability of an axial tensile steel member is studied. The influence of partial safety factors of standard EUROCODE 3 and EN 1990 on the reliability of design is examined. The reliability is determined, applying probability procedures based on Monte Carlo method. The measure of reliability is the probability of the structure failure. The failure probability of designed steel members is a function of input random material and geometrical characteristics obtained by experimental research. The failure probability carried out is compared with target probability given in standard EN1990. A simplified problem of a member loaded by permanent load action combined with a longtime leading single variable load action is considered for the elaboration of the parametric study.
