Przykład obliczeniowy opisuje obciążenia wiatrem działające na model grupy budynków w kilku kierunkach. The model consists of eight cubes. The velocity fields obtained by the RWIND simulation are compared with the measured values from the experiment. The experimental data are measured using a thermistor anemometer in the wind tunnel.
Przykład obliczeniowy opisuje obciążenia od ściskania ścian budynków w układzie tandem, zlokalizowanych w poziomie terenu. The buildings are simplified to rectangular objects and scaled down while maintaining the elevation ratios. The pressure distribution on the walls of the model of a medium-high building was conducted by an experiment. The chosen results (pressure coefficient Cp) are compared with the measured values.
Przykład obliczeniowy opisuje stacjonarny przepływ wokół wieżowca w postaci bloków miejskich (model w skali). The example is given by the Architectural Institute of Japan (AIJ). The chosen results (velocity magnitude) are compared with the measured values.
Przykład obliczeniowy opisuje stacjonarny przepływ wokół izolowanego budynku (model w skali). The chosen results (velocity magnitude) are compared with the measured values.
Symetryczna płytka konstrukcja składa się z ośmiu równych prętów kratownicowych, osadzonych w podporach przegubowych. The structure is loaded by a concentrated force and alternatively by imposed nodal deformation over the critical limit point when the snap-through occurs. Imposed nodal deformation is used in RFEM 5 and RSTAB 8 to obtain the full equilibrium path of the snap-through. The self-weight is neglected in this example. Determine the relationship between the actual loading force and the deflection, considering large deformation analysis. Evaluate the load factor at the given deflections.

Rozważ belkę ASTM A992 W 18×50 dla stałych i równomiernych obciążeń stałych i ruchomych, jak pokazano na Rysunku 1. The member is limited to a maximum nominal depth of 18 inches. The live load deflection is limited to L/360. The beam is simply supported and continuously braced. Verify the available flexural strength of the selected beam, based on LRFD and ASD.
Na górnym końcu zamocowany jest pręt o przekroju kwadratowym. The rod is loaded by self-weight. For comparison, the example is also modeled with the concentrated force load, the value of which is equal to the gravity. The aim of this verification example is to show the difference between these types of loading, although the total loading force is equal.
Pręt o zadanych warunkach brzegowych jest obciążony momentem skręcającym i siłą osiową. Neglecting its self-weight, determine the beam's maximum torsional deformation as well as its inner torsional moment, defined as the sum of a primary torsional moment and torsional moment caused by the normal force. Provide a comparison of those values while assuming or neglecting the influence of the normal force. The verification example is based on the example introduced by Gensichen and Lumpe.
Rozważmy sztywną rurę rusztowania, zamocowaną u dołu za pomocą podpory węzłowej rusztowania i obciążoną zarówno momentem, jak i siłą. Calculate the maximum radial deflection by exceeding the capacity of the scaffolding support.
Wspornik o profilu dwuteowym jest podparty na lewym końcu i obciążony momentem obrotowym. The aim of this example is to compare the fixed support with the fork support and to investigate the behavior of some representative quantities. Comparison is also made to the solution by means of plates. Small deformations are considered, and the self-weight is neglected. Determine the rotation in the midpoint of the cantilever, and in case of the member entity with warping, determine the values of the primary torsional moment, the secondary torsional moment, and the warping moment both on the left end (point A) and the right end (point B).
Szeroka płyta z otworem jest obciążona w jednym kierunku przez naprężenie rozciągające. The plate width is large with respect to the hole radius, and it is very thin, considering the state of the plane stress.
